An explosion in the head of a Dallas police officer killed the man, but he had no injuries and was released from the hospital, police said.
The explosion occurred in a vehicle parked on the side of the street where the officers were responding to a 911 call about a man with a gun and a knife, police Chief David Brown said.
An officer got out of his patrol car and saw the man with the gun, Brown said at a news conference Thursday night.
The officer immediately shot the man in the chest and killed him, Brown added.
The Dallas Police Department said Thursday that the man’s name was not released pending notification of family members.
The man was taken to Baylor University Medical Center for a medical examination and a post-mortem examination, Brown wrote in a news release.
The medical examiner’s office has not yet announced an official cause of death, the department said.
