1 p.m.

Houston's police chief says one of four narcotics officers shot while serving a search warrant at a suspected drug house has been struck by gunfire two other times during his career.

Police Chief Art Acevedo said Tuesday that the 54-year-old police supervisor, whose name hasn't been released, was also shot in 1992 and 1997. Acevedo didn't provide details of the other shootings.

Acevedo says that the officer told him in a note that he had to go into the house Monday after his colleagues were shot because he knew his "guys were down."

Acevedo described the officer as "tough as nails."

He says: "The only thing bigger than his body, in terms of his stature, is his courage."

8:30 p.m.

Houston's police chief says two suspects are dead after a shooting that injured five officers, including four who were hit by gunfire.

Chief Art Acevedo says the suspects were killed after firing at officers serving a search warrant at a southeast Houston home where authorities allege black tar heroin was being sold.

Four of the officers were shot and a fifth suffered a knee injury.

Acevedo says two of the officers who were shot were hit in the neck by gunfire and are in critical but stable condition.

The other three officers are in stable condition and are expected to make a full recovery.

Acevedo didn't immediately have additional information about the suspects.

Acevedo says the officers came under fire just after forcing open the home's front door.

Four police officers were shot Monday afternoon in Houston and two of three suspects are dead, authorities say.

A third suspect, however, remains inside the house where officers were attempting to serve the warrant at around 4 p.m. Monday.

Houston police Chief Art Acevedo confirmed the shootings, tweeting, “We have had several officers shot. Please pray for officers.”

The Houston Police Department, in a tweet, said police were responding to a scene at 7800 Harding where “officers have been struck with gunfire following an encounter with a suspect.”

The injured officers were taken to hospitals, the tweet said.

Authorities said two of the officers are in critical condition.

A tweet from the city's Police Officers' Union said one of the injured officers was flown to a hospital by helicopter.

The other three were in stable condition, the city's police union president said.

Gov. Greg Abbott issued a statement in which he said, "This evening’s horrific attack on police officers is a solemn reminder of the service and sacrifice our brave men and women in law enforcement make every day to keep us safe."

"The city of Houston and the Houston Police Department will have whatever state resources they need to bring swift justice to those involved," he said.

"I ask all Texans to join Cecilia and me in praying for the officers injured, and for the continued safety of all law enforcement officers who protect our communities.”

Attorney General Ken Paxton said in a statement he was "deeply troubled to learn that five Houston police officers have been wounded in the line of duty this evening."

"The thoughts and prayers of countless Texans are with the officers, their families, and the Houston Police Department. May this tragic event serve as a reminder of the courage with which law enforcement officials serve each day," he said.
