Police in the US State of California say 12 people have been killed in a shooting at a bar in the city of Thousand Oaks.
Among them is a police officer who was planning to retire next year.
Sergeant Ron Helus worked on the force for nearly three decades.
The gunfire broke out during a country music night in The Borderline Bar and Grill at around 11:20 local time last night.
It was packed with hundreds of people when the gunman attacked.
Police say they've identified the suspected shooter as 28-year-old Ian David Long, a former Marine.
Authorities believe he killed himself after opening fire
