Boulder Police Sgt. Fred Gerhardt says witnesses on Wednesday reported a man was dressed as a leprechaun and pretending to shoot at people with his fingers.
Witnesses told police the man may have made obscene gestures.
Gerhardt says they likely called police because the man "was acting bizarre."
Officers did not find anyone matching the description of the leprechaun.
Gerhardt says this is the first time Boulder police have received a complaint about a leprechaun.
