Seven people including two young men in a Dillard University dorm room were robbed at gunpoint in separate incidents striking neighborhoods from Carrollton to Gentilly on Thursday and Friday in New Orleans.

A 66-year-old woman was the first to fall victim near the corner of Usrulines Avenue and North Villere Street in Treme around 9:45 a.m. on Thursday. Police said that she was approached by an unknown man armed with a handgun who demanded her belongings. When she resisted, he knocked her to the ground, dragged her, then fled in a vehicle with her purse.

Then another suspect approached a 31-year-old man near the corner of Marais Street and St. Roch Avenue around 1 p.m. and forced him to turn over his money.

In Central City, a man hopped out of a vehicle in the 2200 block of Magnolia Street at around 4:15 p.m. and forced a 25-year-old man to turn over cash.

In Carrollton at around 7 p.m., a 54-year-old woman pulling into her driveway in the 1600 block of Dublin Street was approached by a man with a gun who pointed it at her and demanded money.

Two more armed robberies happened in the early morning hours Friday. First two 18-year-olds in a Dillard University dorm room were visited by two armed men who demanded their property. One victim was kicked several times and the other was struck, police said. The suspects fled with an iPhone 6, money and a wallet filched from the victims’ pockets.

Officer Frank Robertson, a New Orleans Police Department spokesman, said the victims knew the perpetrators and were involved in some sort of a dispute with them. He added that detectives were “aggressively” working leads in the case.

Finally at around 4:30 a.m. in Bayou St. John, a woman was approached from behind in the 2700 block of Orchid Street by a man who put a gun to her neck and demanded her possessions. Police said he fled with her purse.
