A severed goat head was found outside of Wrigley Field early Monday, hours before the Cubs opened their home schedule.

Chicago police treated the incident as a prank, according to the Associated Press. A similar incident took place a few years ago, according to the Chicago Tribune.

The goat's head was reportedly found on the Harry Caray statue that is located outside of the park.
