A 48-year-old Fairfield man accused of threatening a lifeguard at Southport Beach on Tuesday afternoon was arrested on charges of second-degree threatening and second-degree breach of peace.

Joseph Gallace, of Cross Highway, was arrested by Westport police earlier in the day on a second-degree breach of peace charge and was released by that department on a promise to appear in court, according to the report. Information on his arrest in Westport was not immediately available from Westport police.

In Southport, Gallace was parked in a van at the beach for a half-hour and then charged toward the lifeguard and asked if the lifeguard had a problem with him. Gallace also yelled obscenities at the lifeguard and threatened to "knock his head off" in addition to other threats, according to the police report.

The lifeguard told police there have been "numerous incidents" with Gallace in the past, and several officers also are familiar with him from other incidents, police said.

Gallace was arrested at Southport Beach about 5:16 p.m. and his van was towed, police said. He was held in lieu of $1,000 bond and was scheduled to appear July 18 in Bridgeport Superior Court, police said.

"He was officially warned not to return to Southport Beach, ever," said police Sgt. Sue Lussier.
