NORWALK — A group of robbers escaped with about $50,000 worth of jewelry Wednesday after a smash-and-grab robbery at the Norwalk Indoor Swap Meet, authorities said.

Four to five men, one of them armed with a handgun, entered the Goldtime store in the Swap Meet, 11600 Alondra Boulevard, about 12:45 p.m., Los Angeles County sheriff’s Sgt. Chris Mouat said.

The robbers ordered everyone to get away from some jewelry cases before they smashed them open and helped themselves to the gold, he said.

They were described as black men in their mid-20s, Mouat added, and they were last seen fleeing in an older-model, gold-colored, 4-door Nissan sedan, possibly an Altima or Maxima.

A group of about seven robbers carried out a similar robbery on Dec. 10 at a jewelry store inside the Pico Rivera Indoor Swap Meet, officials said.

The men fled in two getaway cars with stolen jewelry, but left one suspect behind who was arrested by deputies.

Officials were looking into the possibility that Wednesday’s robbery in Norwalk was related to the Pico Rivera crime or any other recent smash-and-grab jewelry robberies.
