Officers in the Birdland area spotted a man Tuesday morning that matches the description of a suspect, according to Sgt. Michael Collins.
That officer lost sight of the man, but another officer spotted him apparently prowling the yard of a home on the edge of Sutter Gate Avenue. When that officer approached, the man fled, jumping fences behind homes along Jones Gate Court.
"We ended up getting a perimeter set up very quickly. We had a fast response from East Bay Regional Parks -- their helicopter is called Eagle One," Collins said. "They were here in a very short time. We had two K-9 officers searching around homes."
Despite that, the man slipped away, leaving police to think he made it inside his home, somewhere near the Sports Park.
Collins said the man is suspected in a number of daytime burglaries, stealing jewelry and sometimes using ladders found near homes to gain access to second-story windows. He said at least one incident occurred on a Saturday, at a time when people are usually home.
Witnesses have given slightly different descriptions of the man, but Collins said police are making progress.
"We're honing in on what his guy looks like," he said. "Slowly but surely, we're putting together the picture of who this guy is and we're narrowing our scope."
Collins described the man as a white young adult, somewhere in his 20s.
Anyone with information is asked to call Pleasanton police at 931-5100.
