Baton Rouge police Friday arrested a second man in a bar fight last weekend that led to the arrest of suspended LSU running back Jeremy Hill.

Robert G. Bayardo, 20, 4000 Lake Beau Pre Blvd., was booked into the East Baton Rouge Parish Prison on one count of second-degree battery, police Cpl. L’Jean McKneely said.

Bayardo was arrested at his home without incident, McKneely said.

“LSU police assisted us the best they could,” McKneely said, “and from there we got the information we needed to identify the second suspect.”

Bayardo was being held Friday evening in lieu of $5,000 bond, prison officials said.

The fight happened at 2:13 a.m. April 27 in the parking lot of Reggie’s Bar, 1100 Bob Pettit Drive. Hill, 20, left the scene prior to police arriving and was later booked with simple battery, police have said.

A cellphone video showed Bayardo knocking a 20-year-old man unconscious after Hill punched the victim, who had been walking away, authorities have said. The video showed Hill and Bayardo giving each other high-fives in front of the victim after he fell to the ground, according to a police report.

Two “independent witnesses” of the fight identified Bayardo as the man who struck the victim in the back of the head, an affidavit of probable cause says. Both witnesses picked Bayardo out of a six-person photo line up consisting of Bayardo and five people with similar features, the affidavit says.

Hill’s attorney, Marci Blaize, has said several people made derogatory comments to Hill the night of the fight, but she has declined to say whether the victim made the comments or what was said.

LSU head football coach Les Miles suspended Hill indefinitely on Monday.

Hill pleaded guilty in January 2012 to misdemeanor carnal knowledge of a juvenile after he and another student engaged in a sexual act with a 14-year-old girl in Redemptorist High School’s locker room. Hill was given a six-month suspended jail sentence, and a condition of his probation had been that he refrain from all criminal conduct, according to court records.
