Jack Nicholson: Grandson's Ex-Girlfriend Seeks Restraining Order

The ex-girlfriend of Jack Nicholson's grandson, Sean Knight Nicholson, has filed for a restraining order, citing domestic violence.

Sean Knight Nicholson was arrested on August 7 in Los Angeles on suspicion of inflicting bodily injury on Elizabeth Lawlor. He was released on $50,000 bail.

According to Lawlor's statement, Nicholson, who allegedly has addiction and schizophrenia issues, attacked her at his Venice, California apartment on July 23. She claims he grabbed her by the neck and head and threw her into a hard object, causing her to lose consciousness and break a tooth.

Lawlor reportedly sent photos of her injuries to Nicholson's mother, Jennifer Nicholson, who called the police. Lawlor was taken to the hospital, where she was treated for her injuries.

The hearing for the restraining order is scheduled for September 2.
