The department’s crime analyst said thefts have significantly risen along the Monterey Road business corridor, with thieves smashing windows and stealing cash registers.

At Betto’s Bistro owner Norberto Hernandez said he stays late because he’s concerned about break-ins.

“We close at 8 and I stay another couple hours, see everything is fine, then go home,” Hernandez said.

Investigators say the number of commercial burglaries was up 270 percent in December and January versus the same period a year ago. They say what’s more interesting is that the break-ins seem to be following a pattern: most happen on Wednesdays between 11 p.m. to 1 a.m. at businesses on Monterey Road.

“As a restaurant going through a pandemic, it’s just terrible. Absolutely terrible,” said Breanna Rose, manager at Willard Hicks restaurant.

Another area seeing a rise in thefts are construction job sites and sporting venues, where police said suspects are breaking into containers to steal construction equipment and landscaping tools.

Police said more than six arrests have been made in connection with the thefts and are seeking six additional suspects.

Authorities offered several tips to businesses, including reporting suspicious activity and to empty cash registers before closing for the night. Meanwhile construction workers are also being asked to secure all containers and tools before the end of their shifts.
