Two pedestrians were assaulted and robbed in separate incidents in Roosevelt early Sunday morning, Nassau County police said.

Police said the first victim, a 38-year-old man, was walking on West Centennial Avenue at 12:35 a.m. when a group of three teenage boys approached him.

The suspects, who appeared about 16 years old, according to police, then pushed the victim to the ground, punched him in the face, and stole his wallet and cellphone before fleeing, police said.

One of the suspects was on a bicycle, while the other two were on foot, police said.

An hour and a half later, a 26-year-old man was assaulted as he walked on Nassau Road near East Roosevelt Avenue, police said.

The suspects began punching and kicking the victim, knocked him to the ground and stole his wallet before fleeing on bicycles westbound on West Roosevelt Avenue, police said.

The suspects were said to all be wearing dark jeans. One wore a sleeveless white T-shirt, while another wore a black-and-white sweater.

In both cases, the victims suffered minor injuries but refused medical attention at the scenes.

Police ask anyone with information about these cases to call Nassau County Crime Stoppers at 800-244-TIPS. Callers will be kept anonymous.
