KIRKWOOD, Mo. (AP) — Authorities in the St. Louis suburb of Kirkwood say no one was injured by a liquid bomb found in a home’s mailbox.

Kirkwood police Detective Bob Bruhy tells KTVI-TV that a woman retrieving her mail Thursday morning found the two-liter bottle filled with a liquid and aluminum foil — what’s typically called a “Drano bomb.”

Police say the woman didn’t touch the bottle and called police, who responded before calling in firefighters and a bomb and arson squad.

Bruhy says the device was removed and disposed of safely.

After the homeowner posted about the bomb on their neighborhood Facebook page, someone who lives a few streets away realized they had picked up a smiliar item from their yard and tossed it in a trash can.
