A thief known for his unique approach - slithering into businesses to avoid motion-activated alarms - has been caught wriggling into a gold exchange and making off with $50,000 worth of silver. Surveillance footage shows the so-called 'snake burglar' crawling on the carpet of Crown Gold Exchange in Riverside, California, about 55 mi east of Los Angeles, sometime last week. The thief broke into a vacant storefront next door, used a hammer to break the drywall, and wriggled into Crown Gold Exchange. He then spent five minutes rummaging through the back room, owner Cesar Meyer told KTLA. The burglar's approach is virtually the same as the one used in at least six robberies in Riverside in recent months, police say. At Body Tan Salon and Spa in November, a man kicked in a side window at ground level and cut through sheet rock before sliding in and emptying the register. California has been plagued by smash-and-grab looters and rising property crimes during the past year. Scroll down for video Surveillance footage shows the so-called 'snake burglar' crawling on the carpet of Crown Gold Exchange in Riverside, California He wriggled around on the floor to avoid motion sensors and left with $50K worth of silver The robbery took place last week at Crown Gold Exchange in Riverside, California, about 55 mi east of Los Angeles Owner Cesar Meyer says the man was inside the store for a full five minutes and broke in through the drywall in a vacant business right next door Police are still investigating if the thief from the gold exchange is the same person who committed the November burglaries. 'This Crown Gold Exchange burglary does appear to be very similar, if not the same, to the suspect in the others back in late November. Our detectives are following up on leads but we have not identified the suspect yet,' Riverside Police spokesman Ryan J. Railsback told DailyMail.com. Video from Crown Gold Exchange shows the man wearing a dark hoodie, dark pants and sneakers. He opens drawers as he remains on the floor, taking things out of them and sliding back out. 'This guy slithered in, crawled on the ground, kind of like Lt. Dan-style, hand over hand, didn't move his legs, and was able to rummage through my entire back room for a full five minutes,' said Meyer, the owner. He's blaming his ADT alarm system for not alerting him. 'There's definitely something faulty, something going on with the ADT motion detectors, because if they're designed to detect motion, this guy is moving around a lot in all of these businesses, and ADT's motion detectors are not picking it up,' Meyer told KTLA. A burglar with a similar 'snake' tactic broke into at least six businesses in Riverside through December. Police are investigating if the gold exchange thief is the same man caught slithering in the lobby of the Rustic Roots hair salon at around 5am on November 26 That same night, he also broke into Body Tan Salon and Spa just down the street He kicked in a glass window and cut through the sheet rock before sliding in and taking all the money from the register Surveillance footage caught him slithering in the lobby of the Rustic Roots hair salon at around 5am on November 26. He seems to have entered and left through a fire escape on the ceiling, KTLA reports. Merchandise was missing, the register was open and $8,000 were gone, according to owner Lori Hajj. Hajj also had security cameras and motion detectors. 'Basically, your sensors have to be, like, in the middle in your business. It's not like a home, it's a business. And because they're so high, it does not detect. The alarm will not sound off,' she said. 'Basically, your sensors have to be, like, in the middle in your business,' said Lori Hajj, who was targeted by the snake burglar. 'And because they're so high, it does not detect. The alarm will not sound off,' she said Suzanna Velarde, who owns Body Tan Salon and Spa just down the street from the hair salon, thinks the same burglar hit her business. Surveillance footage shows someone crawling past the front door of her business on the same night as the hair salon robbery. 'He crawled all the way on the floor to the register. He took all the money,' she said. 'I couldn't even sleep at night.' Riverside police have not identified any suspects in the burglaries.
