A woman attempting to reconcile with her estranged husband handcuffed herself to him as he slept and then bit him on his torso and arms as he phoned for help, police said.

Helen Sun, 37, told police she wanted to have a conversation with Robert Drawbaugh without him leaving. She changed the locks on their bedroom door and, while he was sleeping Monday, handcuffed herself to him, authorities said.

Drawbaugh was able to dial 911 from his cell phone. Nearly out of breath, he told dispatchers he woke up handcuffed, was still bound to his wife and was holding her down, according to a recording released by police. Dispatchers heard Drawbaugh scream in agony, apparently as his wife bit him.

"Owwww!" Drawbaugh shouted repeatedly. "Are they almost here? Oh God. I need help!"

Asked by dispatchers why his wife was attacking him, Drawbaugh said he divorced her. He also said she has a history of violence.

Officers who went to the home in Fairfield heard Drawbaugh screaming for help and forced their way in through the front door.

Drawbaugh was treated at a hospital, police said. Sun told investigators that restraining Drawbaugh was the only way she could get him to speak to her, authorities said.

Police charged Sun with third-degree assault, disorderly conduct, reckless endangerment and unlawful restraint. She was being held on $15,000 bond after an appearance Tuesday in Bridgeport Superior Court, according to a court clerk. Sun was represented by a public defender who did not immediately return a message left by The Associated Press.

Drawbaugh, 32, has been living in Los Angeles and came back to Connecticut about a week ago, police said.

He told police his wife is obsessive and a danger to him and his friends and family. He said his wife hired private investigators to follow him, according to police.

Police said they were called to the house on Valentine's Day last year when the couple got into a fight and in December 2007 when they got into an argument over a Christmas tree.

The status of their divorce is unclear.

Sun's mother said the couple had been married about eight years.
