Los Angeles Police Department officials are looking for a man suspected of robbing taxi drivers in the North Hollywood area.
The first incident occurred about 11:30 p.m. June 9, when a man hailed a taxi near the North Hollywood Metro Red Line Station.
The man asked the taxi driver to drive him a short distance, and upon arriving at the location, the man simulated a handgun and demanded money. The man got away and the driver was not injured during the incident.
About 2:15 a.m. June 17, authorities believe the same man robbed another taxi driver using the same tactics. The driver in the second robbery suffered minor injuries, officials said.
"As the taxi was going to get change for him, he punched the driver," LAPD Detective Jennifer Hammer told KTLA.
The injured taxi driver attempted to speed off to get away, but crashed because the alleged robber had his hands on the steering wheel.
"In both instances he flagged them down and gave them directions as he drove he didn't really give a specific address," Hammer explained. "He's done it not once but he's done it twice and so in my mind he will do it again, and we need to find out who this is before someone does get hurt or if it is a real gun that there's a tragedy. We don't want someone to get hurt."
The alleged robber is described as being a 25-year-old black man with black hair. He is about 5 feet 9 inches tall and weighs about 160 pounds. He has a goatee and was last seen wearing a necklace with a large charm and a ring on his right hand.
Anyone with information about the crimes can call 818-754-8424.
