Police are searching for a man suspected in a series of office burglaries in Palo Alto, Burlingame and San Mateo and who has been posing as an IT or construction worker.
The man has carried a laminated badge or ID card that he wore on a lanyard or clipped to his clothes in order to gain access to the offices, police said.
When confronted, he has told people he was there to check Internet lines, according to Burlingame police Sgt. Don Shepley. Detectives have nicknamed the man the "IT Poser."
The burglar has stolen computers and wallets from office buildings in Palo Alto, San Mateo and on the east side of Burlingame, Shepley said.
The man wears his hair in a ponytail and has tattoos on his arms and torso, Shepley said. He may drive a white Ford Taurus.
