A 20-year-old from Hicksville was arrested Tuesday, two hours after police said he robbed a commuter walking toward the Hicksville Long Island Rail Road station.

Dominick Marinelli, of 65 Combes Ave., was arraigned Tuesday on second-degree robbery and bail was set at $50,000 cash or bond. He was represented by Legal Aid.

Nassau County police said Marinelli robbed the 49-year-old man as he headed to the station to take a train home from work, attacking the victim from behind as he neared the parking lot at about 12:35 a.m.

Police said Marinelli followed the victim, pushed him against a parked car, struggled with the man, then stole his wallet and backpack before fleeing the scene. The victim immediately called 911 to report the robbery -- and police said officers found Marinelli a short distance from the scene, where he was identified by the victim.

The arrest was made at 2:37 a.m., police said.

Police said the victim suffered cuts and scrapes during the robbery, but declined medical attention at the scene.
