A flash mob of masked thieves were caught on video using a bird call during a recent smash-and-grab at a Macy’s store in Southern California.

Nine masked males struck the store at the Westfield Fashion Square in the Sherman Oaks neighborhood of Los Angeles just after 12:30 p.m. Thursday, KABC-TV reported.

The suspects are seen on video filling bags with stolen merchandise as bystanders look on in shock. 

In one video recorded by a witness, a suspect can be heard making a bird call before someone yells, "Let’s go!" The suspects then run out of the store with bags full of stolen items.
