Atlanta Hawks reserve forward Josh Powell was arrested before Saturday night's game at Philips Arena after police say he repeatedly refused to move his car that was blocking an ambulance.

The Riverdale High School graduate was charged with failure to obey an authorized officer directing traffic, failure to yield to emergency equipment and obstruction, Atlanta Police spokesman Curtis Davenport told the AJC.

According to police, Powell was attempting to turn onto Park Avenue West from Marietta Street late Saturday afternoon but was unable to do so because of heavy traffic caused by this weekend's SEC basketball tournament. Powell's car was blocking the clogged intersection, making it impossible for the ambulance to proceed, Davenport said.

"The officer approached Mr. Powell's vehicle and told him numerous times to go straight through the intersection ... [he] refused and was placed under arrest," Davenport said.

Powell, 28, was not in uniform as the Hawks took the court early Saturday evening against the Portland Trail Blazers . The seven-year NBA veteran signed with Atlanta last summer after winning two championship rings as a back-up forward/center for the Los Angeles Lakers.

Hawks spokesman Arthur Triche  said the organization was made aware charges had been filed against Powell but declined additional comment.

Powell has bonded out of jail, Channel 2 Action News reported Sunday.
