FREMONT-- A man being served a felony warrant escaped from police at his home on Sunday despite SWAT teams surrounding and gassing the house, police said.

Just before midnight, patrol officers arrived at the home on the 5600 block of Cello Way to serve 30-year-old Tin Nguyen with a felony no-bail warrant for a drug charge parole violation, Spokesperson Geneva Bosques said.

As officers approached the home and tried to serve the warrant, Nguyen ran out the back door and was confronted by additional officers, Bosques said. Nguyen ran back into the home, holding an object that police have since been unable to identify.

Patrol officers went into the home and found all bedroom doors closed, prompting call in the full SWAT team, Bosques said. The SWAT team arrived just after midnight, searched and eventually gassed the home, but were unable to find Nguyen.

"The SWAT team had full containment on the house, our only estimation is that he went into the attic and did a rooftop jump," Bosques said. A neighbor also reported seeing someone jumping backyard fences around that same time.

Police expanded their search area to include the entire neighborhood but were still unable to fine the suspect, so the search was called off about 7 a.m., Bosques said.

Nguyen is a reportedly documented Vietnamese gang member out of Union City, Bosques said. A detailed description of the subject was not immediately available.

Anyone with information about Nguyen's whereabouts may call Fremont police at 510-790-6900.
