Police Chief David Brown says a suspect in the overnight attack that killed five police officers, wounded seven others and wounded two civilians said he was upset over the recent police shootings of black men and wanted to kill white people.
Brown said at a news conference Friday that the suspect made the comments before he was killed by an explosive used by police.
He says his department and their families are grieving and that the divisiveness between police and the public must stop.
Authorities say snipers opened fire on police officers during a peaceful protest in downtown Dallas Thursday night over the recent fatal shootings of black men in Louisiana and Minnesota.
Authorities say three other suspects were arrested.
Police Chief David Brown says authorities are still not certain that they have identified everyone involved in an attack on a downtown protest march that killed give police officers.
Brown said Friday that investigators have not ruled out that others may have been involved in the attacks that left a total of 12 officers and two civilians shot.
Dallas Mayor Mike Rawlings says an overnight standoff with one suspect in a parking garage ended when police detonated an explosive about four hours after the attack began. Authorities say the explosive was attached to a robot to protect officers.
Brown would not reveal any details about other potential suspects that have been detained by police and interviewed.
