There was a court appearance for an Albany teen accused of slamming a skateboard into the skull of an Assistant Albany County DA earlier this month.
Zamari Coffin entered a not guilty plea to robbery and assault charges.
Police say ADA Vincent Stark needed emergency surgery to have a portion of his skull removed.
He had a fractured eye socket and cheekbone.
He's experiencing a loss of hearing and has a serious brain injury.
Coffin was sent to the Albany County Jail without bail.
Two others were involved in the attack.
No other arrests at this point.
