ATCHISON COUNTY —The Bureau of Alcohol, Tobacco, Firearms and Explosives and the Atchison Police Department have issued a $5000 reward for information leading to the arrest and conviction of those responsible for detonating an explosive device in the 100 block of North 8th Street in Atchison.

Just after 2:30a.m. Friday, Atchison Police and Fire were dispatched on reports of an explosion in the downtown area. Upon arrival, authorities found considerable damage to numerous structures in the 100 block of North 8th Street.

Investigators from the Kansas State Fire Marshal’s Office and United States Bureau of Alcohol, Tobacco, Firearms and Explosives also responded to the scene and began a “post-blast” investigation.

Investigators determined the cause of the explosion was likely an improvised explosive device placed outside the Hair Spital Barber Shop, 120 North 8th Street.

The blast shattered windows and spread debris across a one block area of downtown Atchison.

Investigators would like to speak to with anyone who may recognize the minivan seen in security videos near the blast moments before the device detonated. The vehicle may be a 2004-2008 Nissan Quest, according to police.

Anyone with information about this vehicle or the explosion is asked to contact the ATF at 1-888-ATF-BOMB (1-888-283-2662), contact ATF through its’ website at www.atf.gov/contact/atftips, or text 63975 using the code ATFKC.
