Former Phillie Lenny Dykstra is claiming he suffered brain damage at the hands of law enforcement officers during an alleged assault three years ago inside a California jail.

Dykstra, 52, added these accusations to a lawsuit he filed in April. In the suit, the former Phillies' outfielder claims he was physically assaulted by six sheriffs at Los Angeles County Jail while in custody in April 2012, according to a TMZ report.

Dykstra, who later served a six-and-a-half-month sentence in federal prison for bankruptcy fraud and other charges, claims six sheriffs entered his jail cell and severely beat him.

In his original lawsuit, Dykstra claimed his teeth were broken, his head was slammed into a wall and he was kicked until he was barely breathing. In his new claims, he added that guards whistled "Take Me Out to the Ball Game" during the 2012 assault, and the beating left lingering effects, including brain damage and eating issues, according to TMZ.

He claimed video of the assault exists, but expressed fear that it was destroyed. He also claimed the corrupt law enforcement officers prevented him from receiving proper medical attention by instructing doctors and nurses to withold care, according to the website.

Dykstra played for the Phillies from 1989 to 1996.
