Actress Katharine Ross has obtained a restraining order against her daughter, Cleo Rose Elliott, after the young woman repeatedly stabbed her in the arm with scissors, according to court documents.
Ross – who is married to actor Sam Elliott – is best known for her roles in iconic films such as The Graduate and Butch Cassidy and the Sundance Kid. Now 71, Ross writes in the restraining order that Cleo, 26, "verbally and emotionally abused me even as a little girl but became increasingly violent at age 12 or 13," and that the problem came to a head earlier this year.
On March 2, Cleo lost her temper, told her mother, "I want to kill you," kicked in a cupboard door in the kitchen and then followed her mother around the house, the court documents state.
Ross says that when she picked up the phone to call police, Cleo cut the phone line with scissors, threatened to poke her in the eye with the scissors and then stabbed her six times in the right arm, "using enough force to pierce my skin through my shirt and leave me with marks that are still visible today."
It's unclear what may have instigated the incident. Ross filed the protective order on March 8 without an attorney. Her spokesman tells PEOPLE he's unfamiliar with the documents and that Ross has no comment.
Until a hearing in the matter on March 30 in Santa Monica, Cleo is ordered to stay at least 100 yards from her mother's home, car and workplace and to not try to contact her. The documents additionally state that if Cleo needs to come by the family's Pacific Coast Highway home for any of her belongings, police officers need to be present.
