OJ Simpson's slain ex-wife's nephew, Sean Brown, was arrested on Tuesday morning for alleged domestic violence against his live-in girlfriend, Amy Johnson, RadarOnline.com has learned.

According to the booking record, Sean was taken into custody in Orange County, Calif. and is being held on $50,000 bail.

"Police responded to a domestic violence call at about 2:30 a.m. and after an investigation was conducted both parties were taken into custody," Commander Stephen Colon of the Santa Ana Police Department told RadarOnline.com.

"Both parties sustained physical injury but neither required hospitalization."

Linda Hogan, appearing on Tuesday's The Today Show to plug her new book, Wrestling The Hulk - My Life against the Ropes, opened up about the alleged abuse she suffered at the hands of her ex, 80’s pro wrestling demigod Hulk Hogan.

“I did not want to end up a statistic, like Nicole Simpson,” Linda, who filed for divorce in 2007, told Matt Lauer about her split from Hogan, who's currently wrestling for TNA.

In the new book, Linda described an incident in which Hulk allegedly tore her shirt and held her down on a bed with his hands wrapped around her throat.

She added Hulk “did not feel remorse -- and to this day he’s never apologized for any of his actions -- but that is something that scared me.”
