Police say the suspect is walking into businesses through open parking garages and once inside, he blends in using fake identification badges.
He's also dressed in business attire -- usually navy blue dress pants and brown dress shoes.
He then searches for unlocked office doors and takes laptops and other electronics, conceals them in a laptop bag, and takes off.
If you recognize him, call the LAPD at 1-877-LAPD-24-7.
