A pair of California teenagers allegedly posed as Immigration and Customs Enforcement agents and robbed Hispanic victims in a brazen set of crimes, according to authorities.

Laurentiu Baceanu and Vasile Alexandru, both 19, were arrested last Thursday hours after allegedly carrying out a couple of robberies between 5 p.m. and 6 p.m., according to Anaheim police.

The two young men approached the Hispanic victims, claiming they were from ICE, before they demanded them to turn over their cash, police said.

Los Angeles' controversial zero cash bail policy is to blame for the recent surge in smash and grab robberies across the city, according to the union representing LAPD officers.

"The elimination of cash bail for these types of offenses is really an invitation to these kind of folks who are inclined to break the law and inclined to do it so brazenly, to push them over to say, 'hey, if I was to get caught, I'm going to be right back out again,'" Los Angeles Police Protective League spokesperson Tom Saggau told Fox News Digital. 

Video captured a mob of thieves swarming a Nordstrom in Canoga Park as they cleared out the store during a destructive robbery on Saturday.

Chaos ensued as a large group of masked thieves clad in dark clothing scrambled around the store, grabbing armfuls of designer clothing, purses, accessories and more.

Los Angeles police received reports of the mass robbery at the Westfield Topanga mall around 4 p.m.

Police said anywhere between 20-50 suspects are believed to be involved, although the exact number has not been confirmed.

Los Angeles police are stepping up enforcement at area malls after a weekend robbery at the Nordstrom at the Westfield Topanga Shopping Center made national headlines.

Los Angeles Police Department Cmdr. Gisselle Espinoza said Saturday’s flash mob acted violently and efforts are underway to find the robbers.

“We are interviewing people and trying to find leads and strategies to find out who these people are,” said Espinoza, who helps lead the LAPD Valley Bureau. “They are savages.”
