SAN DIEGO - Authorities Wednesday are investigating a burglary at a Clairemont-area check-cashing store and believe the culprits may have tunneled in from a business next door.

San Diego police said they received a report of a burglary at 7:49 a.m. in the 5100 block of Clairemont Mesa Boulevard. SDPD Sgt. Andra Brown said the thieves broke into the Fashion Hair Design salon, and then made a hole through a back wall in order to get into the Check Into Cash store. Police said a safe with an undetermined amount of money was stolen from the business.

Surveillance video captured a truck loaded with a large safe. Cameras caught part of the action happening near the checking business, and the video shows one of the thieves wearing dark clothing.

"I see people coming out of the alley, break into the back door, one [person] came into the front door. They were in there for 10 minutes and they left, came back with the truck," said Peter Celecki, manager of the bar next door.

He added, "I guess the whole thing probably took half an hour. They were pretty brave.  There's a lot of cars going up in front to the laundromat – this and that – and nobody knew what was going on inside."

Brown confirmed the Check Into Cash business was robbed earlier this month. A female suspect in that case was taken into custody.

Police in Chula Vista said they also had a report of a safe taken from their city Wednesday morning as well.

Officers said the safe was taken from the Wings and Things restaurant at 2315 Otay Lakes Road. It had been bolted to the floor in the manager's office. Burglars punched out a door lock to gain entry into the restaurant.

Investigators have not said if the two incidents are related.
