Two men pretending to be San Jose police officers walked into a Petaluma woman's home Thursday evening, then fled when questioned by a police dispatcher, police said.

A 66-year-old woman on Stuart Drive had left her front door unlocked Thursday evening, and the men apparently walked right in a little after 6 p.m., said Sgt. Ken Savano.

The two men identified themselves as San Jose police officers, providing identification as proof, police said. But the men were not in uniform and the identification looked suspicious to the woman, so she called 911.

One of the men got on the phone with the dispatcher and said they were there to check on the woman's welfare, according to a statement released by the police department. When the dispatcher began questioning him, however, he hung up and the two men fled in a white pickup truck with blue stripes near the bumper, police said.

It doesn't appear anything was stolen or damaged, Savano said.

Petaluma Police contacted the San Jose Police Department and confirmed they didn't have any officers in the area.

Savano urged residents to lock their doors and beware such scams. When contacted by police officers in plain clothes, ask to see photo identification, he said.

"It's a good opportunity to remind people that it's always OK to verify who we are," Savano added.

Police are still looking for the suspects. Both were described as Hispanic men in their thirties with black hair and brown eyes. Both were about 5 ft. 7 inches and weighed around 155 pounds, police said.

They asked that anyone with information call the Police Department at 778-4372.
