Police were called after Marston allegedly attacked his on-again, off-again Playmate of the Year girlfriend Claire Sinclair.
The cops saw visible bruises and injuries on Sinclair. While Marston said the two had been arguing, he didn’t admit to hitting her.
Sources told TMZ that Sinclair said Marston punched her, kicked her in the stomach, and would not let her leave the residence they share. Sinclair called family members after the attack and her family called the cops.
Marston was arrested, after a brief investigation, for misdemeanor domestic violence at 11:15 p.m. and was booked at a nearby police station.
He was released on $20,000 bail a few hours later.
