Police are warning the public to stay vigilant as armed robbers have been targeting taco vendors in Los Angeles.

Over the past 10 days, four different taco vendor stands were robbed at gunpoint, according to the Los Angeles Police Department.

The vendors were located along the Florence Avenue corridor at Crenshaw Boulevard, Grammercy Place, and Normandie Avenue, said LAPD.

The robberies all took place between 12:40 a.m. to 2:40 a.m. as the vendors were closing up their stands for the night, authorities said.

In each case the thieves brandished a gun, took cash and then fled in a vehicle, police said.

Authorities are asking locals to be aware of their surroundings and to contact the police if they are targeted.

Anyone with information is asked to contact 77th Street robbery detectives at 323-786-5422.
