A man who allegedly tried to throw his girlfriend off the balcony while embroiled in an argument at their Waikiki apartment has been charged with attempted murder and arrested on an unrelated warrant, police said.

At 10:15 p.m. Friday, a 25-year-old woman was taken to an area hospital and treated for her injuries.

Police charged Bryan Adam Roudebush, 23, who was being held in lieu of $100,500 bail, with attempted second-degree murder following the incident at their apartment at 2611 Ala Wai Blvd., police said.

The woman managed to escape and fend off the attack. She received help from a neighbor, police said.
