A suspect in the Dallas police shootings has reportedly shot himself after an hours-long standoff with officers in a garage.
Police chief David Brown said the suspect had threatened to kill more police and was alternating between exchanging gunfire with officers and attempting negotiations.
Journalists at the scene of the garage next to El Centro college reported Swat teams were standing down, and several US media outlets reported the suspect had been "neutralised".
Local KDFW and Fox News, quoting police sources, said the shooter had taken his own life.
Brown said at an earlier press conerence that the suspect told police "the end is coming" and that more were going to be hurt and killed. Brown said the suspect also told police "there are bombs all over the place in this garage and downtown."
"This suspect we are negotiating with for the last 45 minutes has been exchanging with us and has not been very cooperative with the negotiations," Brown said.
Police said they were questioning two occupants of a Mercedes they had pulled over after the vehicle sped off on a downtown street with a man who threw a camouflaged bag inside the back of the car. A woman was also taken into custody near the garage where the standoff was taking place.
Brown stressed that police were not confident they had apprehended all of those involved in the shooting.
