Nassau County police said the mechanic, Christopher Hicks, 32, was arrested by Fifth Precinct officers a short time later at his home on North Corona Avenue in Valley Stream. He was charged with first-degree attempted assault, second-degree criminal possession of a weapon, first-degree reckless endangerment and two counts of second-degree criminal mischief.

Hicks was ordered held without bail at arraignment Tuesday in First District Court in Hempstead. The identity of his defense attorney could not be determined through online court records.

Police said that after Hicks was fired he “picked up a muffler” and threw it at a car being worked on in the shop, causing $3,000 worth of damage to the vehicle. Hicks then exited the shop, went to his own car and got a handgun, police said.

Moments later police said Hicks returned and fired two shots into the bays where employees were working. One of those shots just missing striking an employee.
