Police Wednesday arrested a teenager accused of using a shotgun in two robberies and an attempted one in the Marigny area on Friday and Saturday.

The 16-year-old boy turned himself in to New Orleans police on Wednesday with his family and an attorney present, Officer Frank B. Robertson III said in a news release.

The first robbery occurred at 12:30 a.m. Friday, when the suspect and a man approached a man in the 800 block of Touro Street, pointed a shotgun and demanded his wallet and other items, Robertson said.

The victim ran away, with all his property and minor injuries, after the suspect and other man struck him three times, Robertson said.

The second robbery occurred at 5:05 a.m. Saturday when the suspect and another man approached a man in the 1900 block of Burgundy Street, pointed a shotgun at him and demanded money, Robertson said.

The victim disarmed the would-be robbers and chased them a short distance, Robertson said.

The would-be robbers returned in a black four-door car a short while later and offered to trade the victim’s cellphone, which they said he dropped while chasing them, for their shotgun, Robertson said.

The victim refused and fired at least one shot from the shotgun at the car’s rear windshield, causing it to shatter, before the would-be robbers drove off, Robertson said.

Detectives identified the 16-year-old as a suspect after a family member falsely reported what happened to the car to police and the damage was consistent with a shotgun blast, Robertson said.

On Wednesday, a couple called police after watching video of one of the robberies on television and said they were robbed at gunpoint Saturday in the 800 block of Frenchman Street, Robertson said.
