15 armed men rob Fremont high-tech firm

Fifteen armed men staged a takeover robbery of a high-tech company in Fremont, tying up employees and escaping with computer components, police said.

The heist happened shortly before 8:40 a.m. Sunday at Unigen Corp. at 45388 Warm Springs Road. The robbers, all dressed in black and armed with handguns and automatic rifles, accosted six Unigen employees in the company's loading dock, police Sgt. Chris Mazzone said.

The men tied up the employees and locked them in a room before spending half an hour loading computer parts into a moving-company truck, Mazzone said.

The robbery was filmed by a Unigen surveillance camera, police said.

The heist is being investigated by police and the California Highway Patrol's cargo theft task force.

Unigen was founded in 1991 and develops advanced modular components and integrated circuitry, according to its website.
