Three people were robbed of property and a car in separate incidents on city streets Sunday and Monday, according to the New Orleans Police Department.

About 10:30 p.m. Sunday, police said, a 29-year-old man was in his car at St. Philip and Treme streets near Louis Armstrong Park when someone knocked on the passenger-side window. Another man then opened the driver’s side door, pulled the man out, took his wallet and cellphone and drove away in the vehicle.

In a separate incident, a group of armed teenagers robbed a man early Monday morning.

About 12:30 a.m., a group of four to five teenagers with semi-automatic weapons surrounded the man, 21, near Roosevelt Place and Orleans Avenue, the Police Department said in a preliminary offense log. One of the youths hit the man in the head with a gun and searched his pockets. They then fled in an SUV with the man’s cash, bank cards, cellphone and wallet.

Finally, a woman was robbed in the 1300 block of Simon Bolivar Avenue about 5 a.m. Monday.

The victim, 45, told police that she was approached by a man with a small gun who forced her to turn over her cellphone and a case with her driver’s license and debit card.
