ST. LOUIS (AP) — A $20 million federal lawsuit filed on behalf of four people arrested during protests following the death of Michael Brown accuses the city of Ferguson and its attorneys of constitutional violations and malicious prosecution. The lawsuit was filed Tuesday, on the two-year anniversary of Brown’s fatal shooting by an officer.

It names the city of Ferguson, prosecutors Stephanie Karr and Patrick Chaissang, and multiple city police officers. The plaintiffs were acquitted of wrongdoing earlier this year.

The lawsuit claims the St. Louis suburb spent more than $120,000 in prosecuting cases against protesters who took to the streets in 2014 following Brown’s death.

A Ferguson spokesman says the city has not reviewed the lawsuit and declined comment.

The suit was filed by the law firm Dowd & Dowd and the nonprofit Arch City Defenders.

SIOUX CITY, Iowa (AP) — Two people have sued Sioux City over its ordinance banning pit bulls. The Sioux City Journal reports that the lawsuit was filed Friday in U.S. District Court in Sioux City.

In it, Jennifer Frost and a woman referred to as Jane Doe ask the court to bar the city from enforcing the ordinance.

The lawsuit urges the court to outlaw the ordinance as a violation of the constitutional right to due process.

The lawsuit says the ordinance, passed in 2008, is inconsistent and bans animals that are not harmful. The ban prohibits residents from having dogs that are at least 51 percent pit bull.

City officials declined to comment about the lawsuit.

PORTLAND, Ore. (AP) — Authorities say a 39-year-old man was arrested after officers who noticed him monitoring a Portland police precinct found weapons and ammunition in his vehicle.

Portland police Sgt. Pete Simpson says Eric Crowl was arrested Sunday on charges of attempted assault, unlawful use of a weapon and unlawful possession of a firearm

According to Simpson, Crowl had been watching and filming officers at the precinct since April and considers himself a “Constitutionalist.”

On Sunday afternoon, an East Precinct sergeant asked an on-duty officer to speak with Crowl. The man who has a police scanner quickly drove away, but returned later to continue conducting surveillance.

Officers went to vehicle and arrested Crowl after finding a rifle, a shotgun, two handguns and hundreds of rounds of ammunition. Court records do not list an attorney for the Portland man.

Public records show he has previously lived in Manhattan, Kansas, and Kansas City, Missouri.

KANSAS CITY, Mo. (AP) — A Kansas legislator says he wants to examine the state’s relatively light oversight of amusement park rides like the water slide on which a 10-year-old boy was killed. Meanwhile, complaints have surfaced about safety issues on the ride.

Democratic state Sen. David Haley of Kansas City said Tuesday that he’s hoping there will be bipartisan support for a review. He said people shouldn’t be risking their lives in having fun at an amusement park. Kansas requires annual inspections of permanent rides. The state Department of Labor is required to randomly audit inspection records.

Caleb Schwab died Sunday at the Schiltterbahn Waterpark in Kansas City, Kansas. He was the son of Republican state Rep. Scott Schwab of Olathe.

House Majority Leader Jene Vickrey said lawmakers’ immediate focus is on supporting the Schwab family.

At least two people who’ve ridden the Verrukt waterslide at Schlitterbahn’s say shoulder straps snapped or popped off during the ride.

Paul Oberhauser told local television station KCTV that the safety restraints on his raft on the Verruckt waterslide weren’t working properly when he rode it on July 26 at the Schlitterbahn Waterpark.

The Nebraska man says his shoulder strap “busted loose” during the ride and he “just held on.” A video shot by his wife shows it loose at the ride’s end. He says he told workers about the loose strap.

Kenneth Conrad told WDAF-TV that he rode the waterslide last year with a friend whose shoulder strap came “completely off.” Conrad’s wife snapped a photo at the end of the ride showing the strap missing. Conrad says he didn’t file a complaint with the park.

The park’s spokeswoman didn’t immediately return a message Tuesday from The Associated Press seeking comment on the claims.

ST. LOUIS (AP) — The owner of Union Station in downtown St. Louis is planning a $45 million aquarium that will feature sharks and thousands of other aquatic species.

Officials with Lodging Hospitality Management say construction should begin this fall, with an opening planned in late 2018.

LMH’s chairman and chief executive, Bob O’Loughlin, said the aquarium is expected to help establish Union Station as a family attraction similar to Navy Pier in Chicago. The St. Louis Aquarium will have shops and restaurants aimed at families also visiting the Arch, City Museum and other downtown attractions.

St. Louis Aquarium will be open year round. The 75,000-square-foot aquarium will have fish tanks containing a combined 1 million gallons of water.

JEFFERSON CITY, Mo. (AP) — Missouri voters can weigh in on whether to hike cigarette taxes and re-impose limits on campaign contributions.

Secretary of State Jason Kander on Tuesday announced those measures and others had enough signatures to get on the Nov. 8 ballot.

One proposal would cap campaign donations at $2,600 to candidates per election and a maximum of $25,000 to political parties.

A proposed cigarette tax hike would phase in a 23-cent-per-pack increase to raise money for transportation. Another would gradually increase taxes by 60 cents per pack, primarily to benefit early childhood education.

Another proposal with enough signatures would prohibit sales taxes on services that weren’t taxed as of 2015.

Supporters of a medical marijuana measure without enough signatures will go to court to try to get it on the ballot.

POTWIN, Kan. (AP) — A couple who rented a Kansas farmhouse is suing a company over an internet glitch that brought them numerous legal problems.

The glitch put the coordinates for the center of the U.S. in the front yard of James and Theresa Arnold near Potwin. The farmhouse became the default location for any website owner that didn’t have a specific IP address.

The Arnolds allege in a lawsuit filed Monday that glitch meant more than 600 million IP addresses became associated with the farmhouse. That led to them being accused over the years of internet-based crimes such as computer fraud and tax fraud, as well as making pornographic films.

The couple is suing MaxMind, which they say is responsible.

The lawsuit seeks damages in excess of $75,000.

TOPEKA, Kan. (AP) — The Kansas Bureau of Investigation says three Salina men have been arrested on suspicion of conspiracy to commit capital murder as part of an ongoing probe by the I-135/I-70 Drug Task Force.

The Salina Journal reports two 22-year-olds and one 24-year-old were arrested Sunday evening and early Monday. All three were arrested without incident and were being held in the Saline County jail on $1 million bond each.

KBI special agent in charge Doug Younger declined to identify the intended victim or provide other information about the investigation.

Young says giving additional details would interfere with the ongoing investigation, but noted additional arrests are possible.

He says 30 to 40 law enforcement officers are involved in the large investigation.

JEFFERSON CITY, Mo. (AP) — Missouri Gov. Jay Nixon is defending his record after the head of the state’s public defender system appointed him to a case in protest of recent funding restrictions.

Director Michael Barrett in a letter last week said budget cuts have prevented his office from hiring enough public defenders for those who can’t afford representation.

So Barrett said he’s appointing former attorney general Nixon to represent indigent clients.

Nixon told reporters Monday that funding for the office went up 15 percent since he’s been governor. Nixon also said about $1.8 million went unspent last fiscal year.

The recent pushback comes after lawmakers budgeted a $4.5 million funding increase for public defenders this fiscal year. Nixon then cut that to $1 million.
