A Sentinel, Okla., man on Thursday shot the town’s police chief four times and was then released from custody after questioning, the Oklahoman reported.

Sentinel Police Chief Louis Ross was shot in the chest three times and in the arm once, but he was wearing a bulletproof vest and survived his injuries.

Sentinel Mayor Sam Dlugonski said police were responding to a bomb threat to the community center, according to the Oklahoman. Police identified the house from which the 911 call came, and broke through the front door.

As police entered a bedroom in the home, a man shot Ross multiple times, according to The Oklahoman.

Police later said that the 911 call did not come from the home they raided, according to Oklahoma television station News 9.

Local media identified the man who shot Ross as Dallas Horton. Raw Story found the Facebook page of a white man who claims to be Horton, but the page appears to have been taken down.

According to the Oklahoman, Dlugonski said he knew Horton and described him as a “survivalist” and a “gun enthusiast.”

Police brought Horton in for questioning following the shooting, but released him without charging him. Police did not find any explosives in the community center but removed at least seven firearms from Horton’s home, according to the Oklahoman.

“Facts surrounding the case lead agents to believe the man was unaware it was officers who made entry,” Oklahoma State Bureau of Investigation said in a news release, according to the Oklahoman.

Ross told News 9 on Thursday that Horton claims he didn’t know police officers had entered his home.

“Don’t know what he heard or didn’t hear screaming from five officers of the law announcing our presence, requesting to see hands,” Ross said.
