Dallas, TX – An active shooter was fatally shot by police after he attacked a federal courthouse building in downtown Dallas on Monday morning (video below).
Police responded to the Earle Cabell Federal Courthouse building for reports of an active shooter at approximately 8:50 a.m., ABC News reported.
Witnesses said they heard gunshots in the parking lot, and that they spotted the suspected gunman crouching down behind vehicles parked in the area, according to WFAA.
“There has been an exchange of gunfire between a suspect and federal officers,” the Dallas Police Department (DPD) confirmed in a tweet.
Cell phone footage recorded by a witness showed the gunman, later identified as 22-year-old Brian Isaack Clyde, as he fired rounds at police while outside the courthouse with a rifle.
Clyde appeared to be wearing a ballistic vest, as well as other tactical gear.
Federal officers returned fire, and Clyde ran across a parking area before he appeared to collapse to the ground.
He was rushed to Baylor University Medical Center, where he was pronounced dead, Federal Bureau of Investigation Dallas/Fort Worth Office Special Agent in Charge Matthew DeSarno said, according to ABC News.
Investigators are still working to identify a possible motive for the attack.
"At this time, we have no information indicating that there are other shooters, other threats to the community," SAC DeSarno noted.
Clyde’s vehicle was located near the courthouse, and is being examined by bomb squad technicians and a bomb squad robot, ABC News reported.
“The Bomb Squad is preparing to do a controlled explosion of the suspect’s vehicle,” the DPD confirmed in a tweet.
No officers or civilians were injured during the attack, WFAA reported.
El Centro College and the courthouse remain on lock down, and at least one nearby building has been evacuated.
