Waterfront Concert promoter, Alex Gray is expected to change his plea today on Domestic Assault charges.

According to WCSH-TV, the 41-year-old is expected to enter a different plea in court today. Gray pleaded not guilty to domestic violence charges in March, and had a court date earlier this month postponed.

The charges are in answer to accusations that he assaulted his girlfriend during an argument in his Portland condo. Police say Gray had demanded to see the woman's cellphone on March 12th. She told authorities that, when she tried to leave, he allegedly kicked her legs out from under her, put a hand on her throat, and banged her head against the floor. A group of people standing outside the condo said they heard raised voices but didn't see what happened.
