One constable deputy was killed and two other deputies were wounded in a shooting outside a Houston bar early Saturday morning, police said.
Houston Police Executive Assistant Chief James Jones told reporters the deputies were trying to arrest someone when a suspect shot them from behind with an AR-15 style rifle. Authorities were still searching for a man believed to be the shooter.
The Harris County constable deputies had been working a “police-related extra job” at the 45 Norte Sports Bar at about 2:15 a.m. when they went to assess a disturbance outside, Jones said.
He said they may have interrupted a robbery and when they tried to detain a suspect and were wrestling with him: “they were ambushed.”
