The incident happened around 12 a.m. Monday at NakeStores, a distributor of Byrna self-defense products on Van Nuys Boulevard. According to the Los Angeles Police Department, security footage shows a masked suspect breaking into the store by throwing a rock through a glass door.
It's unclear if that person worked alone or if they had a getaway driver.
Police could not say if anything was taken, but the store sells less-lethal guns, rifles, pepper sprays and other items used for self-protection.

Monday's burglary marks the third time the business has been hit within a year. Last week, five burglars broke in and rummaged through the store.
Store owner Mike Mahfoud told Eyewitness News the thieves made off with several boxes of products.
Police could not say whether the two latest burglaries were connected. No arrests have been made.
This incident comes on the heels of break-in after break-in at homes and commercial businesses this year across Southern California.
Over in West L.A., the LAPD has issued a Community Alert amid a surge in burglaries in upscale neighborhoods such as Bel Air, Brentwood, Pacific Palisades and beyond.
The department says these burglaries appear to be the work of an organized crew of 2-4 unidentified men who target unoccupied homes using a Wi-Fi jammer to disrupt security cameras.
