Tributes have been paid to “hero” police officer Ron Helus, who was killed alongside 11 others in America’s latest shooting.
Sgt Helus ran into Borderline Bar and Grill in Thousand Oaks, California, to help other victims after the gunman fired shots at revellers.
Sheriff Geoff Dean said Sgt Helus "undoubtedly" saved lives by going in to confront the gunman. He was hit with multiple gunshots.
Sheriff Dean told reporters at the scene of the shooting on Thursday: “Ron was a hard-working, dedicated sheriff sergeant.
“He was totally committed. He gave his all and tonight – as I told his wife – he died a hero because he went…”
A visibly emotional Sheriff Dean then broke off mid-sentence as he fought back tears.
Taking a few seconds to compose himself, he continued: “…he went in to save lives.
“To save other people.”
Sgt Helus was shot shortly after he entered the crowded bar in Thousand Oaks, a suburb 40 miles south of Los Angeles. He died in hospital early on Thursday.
Sgt Helus was a 29-year veteran of the force with a wife and son. He had planned to retire within the next year, Sheriff Dean said of his long-time friend.
Journalist Kyle Jorrey posted a picture of Sgt Helus on a fishing trip from his Facebook page.
"While others ran," he wrote, "he went inside to take on the shooter. Now he’s gone. Heartbreaking."
Under another image of Sgt Helus posted on Facebook, people paid tribute to his bravery.
"We thank you for the bravery you showed," David Sanchez wrote, "as you ran to the aid of those in need placing your own life in harm's way. It's men and women like you that deserve all of our gratitude and respect and admiration."
Pierre Letourneau wrote: "He probably did what his heart told him to do."
Brandon Gillman said: "The true definition of courage!"
Witnesses described the terrifying moment the murderous gunman “came out of nowhere” and started shooting, causing a panicked melee.
As well as the 12 fatalities, about 10 people were thought to have been injured in the attack.
The gunman was also killed. Police said he had a gunshot wound, though it was not clear whether he killed himself or was shot by officers.
