OAKLAND, Calif. (KCBS) – The condition of a Fremont police officer who was shot while attempting to arrest a man in Oakland on Friday has improved slightly, Fremont police spokesman Detective Bill Veteran said today.

Veteran said 39-year-old Officer Todd Young is now in serious but stable condition at Highland Hospital in Oakland. He will have another surgery later today.

On Sunday, Young underwent bladder surgery, and the procedure was successful, Veteran said.

Young was shot when he and another officer attempted to arrest 20-year-old Andrew Barrientos at 2009 Auseon Ave., near Bancroft Avenue, in East Oakland at about 2:30 p.m. Friday.

Barrientos was eventually arrested in San Diego County near the Mexican border at about 2 p.m. Saturday. He’s still in San Diego County and is expected to be brought back to Alameda County to face charges later this week.

Young has required more than 60 pints of blood because of the injuries he suffered, and donors have turned out in droves at blood centers across the Bay Area to help out, Red Cross spokeswoman Sara O’Brien said.

O’Brien said people have donated blood for Young at centers in Oakland, Pleasant Hill and Pleasanton over the past few days. She expects similarly high turnout when the Fremont-area blood bank at 39227 Cedar Blvd. in Newark opens at noon today for the first time since Young was shot.

“We’re expecting a lot of local residents to donate,” she said.

O’Brien said there’s also been “amazing” support for Young in San Jose and it’s expected that a previously scheduled blood drive at San Jose City Hall on Wednesday will now be in Young’s honor.
