DALLAS — A gunman killed by a police-detonated explosive after a violent night in Dallas left five police officers dead and at least nine other people injured said he wanted to kill white people and was working alone, Police Chief David Brown said at a press conference Friday.

The man, identified as Micah Xavier Johnson, allegedly said he took issue with Black Lives Matter and two recent police shootings of African-American men. Johnson, 25, was upset with white people and wanted to kill them, especially officers, the Dallas Police Department chief said.

The man also claimed to be working alone and said police would eventually find IED's in the city.

Police found no such explosives during a primary and secondary sweep, Dallas police Maj. Max Geron said earlier in the day.

The man may have been one of two snipers who fired "ambush-style" from an "elevated position."

Three people have been arrested, the Associated Press reports.

Additional information on those detained will not be released until investigators developed a clearer understanding of those involved and their motives, Brown said.

The man made the comments before he was killed by an explosive used by police following an hours-long standoff, Brown said.

Police initially cornered the man and attempted to negotiate with him for hours, but "saw no other options" and decided to use a "bomb robot" out of fear that more officers could be killed or injured if they approached him, Brown said.

Reports that the man killed himself after the bomb went off were inaccurate, and investigators concluded the explosion killed him, Brown said.

Snipers opened fire on police officers Thursday evening during a protest over the recent fatal police shootings of black men in Louisiana and Minnesota.

Five officers were killed, seven others were injured, and two civilians were shot.

The Dallas Police Department and their families are grieving, Brown said, adding that the divisiveness between police and the public must stop.
