The New Orleans Police Department arrested three suspects in two Friday stickups: an armed robbery and carjacking in Holy Cross and an armed robbery in eastern New Orleans where the robbers also tried to steal the victim’s car.

Nishawn Critney, 20, and two male juveniles, ages 14 and 15, were booked on counts of both armed robbery and armed carjacking.

In the first robbery, which took place about 11 a.m. Friday, a woman, 57, was getting out of her car in the 13200 block of Willowbrook Drive when a black Nissan Altima drove up. Two of the car’s occupants approached her, one armed with a handgun, and demanded her possessions and her keys. She complied, but the suspects fled in the Nissan after trying to start her car.

The second incident, a robbery and carjacking, took place about 12:30 p.m. Friday near Reynes and Burgundy streets in the Holy Cross neighborhood, when a 33-year-old construction worker saw four men nearby.

As he tried to get to his pickup truck, the four men, one armed with a gun, demanded his belongings. He complied and then was struck by the assailants, who drove off in his truck, a 2001 white Chevy Silverado.

About four hours later, an NOPD officer attempted to stop a black Nissan Altima that matched the description of the vehicle driven by the Willowbrook Drive robbers. The driver refused to stop, so the officer called for assistance, and after a short car chase, the Nissan crashed at Lake Forest and Michoud boulevards.

The driver and four passengers ran off into the nearby woods, but Critney and four male juveniles, two 14 and two 15, were apprehended by SWAT and K-9 units and officers from the NOPD’s 5th District and the Multi-District Gang Unit Task Force.

Detectives linked Critney and one 14-year-old and one 15-year-old to the two robberies and carjacking. They determined that the other two juveniles were not involved in the incidents and released them.

The investigation is ongoing, and detectives are trying to determine if the three are responsible for any other crimes.
