A pair of stab-happy livery cab robbers are on the loose in the Bronx, and police are asking the public for help finding the suspects after a string of attacks. In the first incident, which took place on September 18, one of the suspects hailed a livery cab near Boston Road and Allerton Avenue at around 11 p.m. and asked to go to East 223rd Street. Upon arrival, the suspect choked the driver by wrapping something around his neck, held an unknown object to his side and demanded cash.

Two days later, the suspect took another livery cab from Boston Road and Warning Ave to the same destination, and again demanded cash upon arrival. When the driver refused, the suspect stabbed the driver in the back, took control of the car and smashed it into a parked car before fleeing. The driver suffered minor injuries.

Three days later, the same suspect, this time joined by a second man, hailed a livery cab at White Plains Road and Pelham Parkway at around 9:30 p.m., with a destination on Magenta Avenue. At the end of the ride, the suspects again tried to choke the driver while demanding cash, and then ripped the cab's security camera out before fleeing.

The suspects are described as a 6-foot black man in his 20s, weighing 180 pounds, wearing a bubble jacket, a fisherman's hat and knit cap; and a 6-foot Hispanic man, in his late 30s, weighing 185 pounds with short black hair and a goatee. Anyone with information is asked to call the Crime Stoppers Hotline at 1-800-577-TIPS (8477) or submit an anonymous tip online.

UPDATE 5:46 p.m.: Police have arrested one of the suspects, 22-year-old Bronx resident Elias Gonzalez, who is being charged with robbery, grand larceny and criminal possession of stolen property. They are still searching for his alleged accomplice, 19-year-old Bronx resident Llonnie Dempster.
