MINNEAPOLIS (AP) — Six people are facing potential criminal penalties in a series of water attacks on drivers and passengers of three pedal pubs in Minneapolis — including one that carried six off-duty police officers.

PedalPub Twin Cities manager Lisa Staplin says the first two attacks on Saturday involved bicyclists who sprayed a driver and passengers with water guns. One passenger was hit in the head with a water balloon.

The third attack was foiled when passengers saw the approaching cyclists and held them until Minneapolis police arrived. Burnsville Police Chief Eric Gieske confirms that six of his off-duty officers were onboard.

The suspects were booked on suspicion of misdemeanor charges ranging from fifth-degree assault to disorderly conduct.
