A man who admonished another man at the Fairfield Public Library for talking on a cell phone Friday was allegedly told by the phone user, "Watch it or I'll cut your throat."

Police were called to the downtown library, but the man who made the threat had already left.

Police did not search further for the man because the complainant didn't know what type of enforcement he wanted.

He only told the officers, "I want you to do your job ... warn him or something."
