A sergeant accidentally fired his gun in the Central District police station in the South Loop, hitting a water pipe that leaked for two hours while police waited on city engineers.
The gun went off around 9:40 p.m. Monday in the Chicago Alternative Policing (CAPS) office at the district station at 18th and State streets, according to police.
No one was injured, but officers noticed a trickle of water from the first-floor ceiling that turned into a gushing stream. The downpour ruined computers and desks, but a damage estimate wasn't immediately available.
The water was turned off overnight and prisoners in the station's holding area were transferred to the police station at 51st Street and Wentworth Avenue, police said. Twelve men and three women were transferred.
Police said the sergeant will likely face discipline within the department.
