A 28-year-old alleged Waikiki pimp has been charged with breaking the bones of a prostitute who works for him and beating her until she lost consciousness.

Demarion Deminique Keyes, of a Lewers Street address, was charged Wednesday with first-degree assault, sex trafficking, and kidnapping.

He was being held at Oahu Community Correctional Center on $500,000 bail. He is scheduled for a preliminary hearing today.

Police arrested Keyes at Honolulu Airport about 4:30 p.m. Monday as he allegedly tried to flee the islands.

The assault began when Keyes forced the woman into a taxi on the corner of Kalakaua and Seaside avenues about 11:10 p.m. Sunday, a police affidavit filed in District Court said.

Keyes took the woman to his home and dragged her into his apartment, telling her she was never going to stop working for him and that he would beat her if she tried to leave, the affidavit said.

Then, for about an hour, Keyes punched, slapped, and choked the woman and struck her with a belt, the affidavit said. The woman told police she lost consciousness during the beating.

When Keyes went into a bedroom, apparently in search of a bat, the woman ran out the apartment and began screaming for help, police said. Keyes fled before officers arrived.

The victim’s mother called police the next day, saying Keyes was at the airport, trying to leave the state. Police notified state deputy sheriffs who detained Keyes.

The victim was treated at Kaiser Moanalua Hospital for several fractures and internal bleeding. A doctor told police the woman sustained serious bodily injury, creating a substantial risk of death, the affidavit said.

The woman told police she was a prostitute and had been working for Keyes for 18 months. She said Keyes beat her because she wanted out of prostitution.
