Suspect dead after gun, bomb attack on Dallas police HQ

Police in the US city said they were "blessed" that nobody was hurt and ruled out any connection to terrorism in the one-man assault that saw gunfire echo around the darkened streets of the sprawling Texas city and left carnage in its wake.

The night of violence began around 12:30 am (0530 GMT) when a man in an armored van rammed into police squad cars at Dallas police headquarters and opened fire.

Shots rang out from several different locations, leading police initially to believe multiple gunmen were involved, before they established the attacker was acting alone.

The mayhem came to a bloody and abrupt end in a restaurant parking lot when SWAT police fatally shot the man -- who has not been officially named -- through the windshield of the armored van shortly before dawn.

"We're blessed that our officers survived this ordeal," Dallas Police Chief David Brown said.

"There are bullet holes in squad cars where officers were sitting. There are bullet holes in the front lobby where staff was sitting."

He described how the man, who gave his name as James Boulware, fired multiple shots at the police headquarters, pausing to reload and apparently using an assault rifle and shotgun.

He "meant to kill officers and took time to discharge that weapon multiple times to accomplish their wanting to harm our officers," Brown added.

Shortly after, police chased the van to Hutchins, a nearby suburb south of the city, where officers surrounded the vehicle and more shots were traded. Several bullets hit police cars but, again, no officers were injured.

Officers tried but failed to negotiate with the man, whose actions were reportedly sparked by a custody battle over his son.

A man claiming to be the man's father, Jimmy Lee Boulware, said his son felt "beaten down" by police and Child Protective Services.

The elder Boulware, 73, also told CBS affiliate KTVT that James struggled to find and keep a good paying job due to his criminal record.

Police have not yet provided a possible motive for the attack.

"He doesn't show to be in our databases on any terrorism watch list or anything like that," Brown said. "So it may have just been a rant."

The Dallas Police Association, which represents Dallas officers, tweeted that the man had "three family violence cases against him. (He) was very disgruntled against law enforcement and the criminal justice system."

At 4:40 am, police sent in an explosives robot to examine a bag that had been found back at the police headquarters. The bag blew up as the robot tried to move it, damaging several cars.

Brown earlier said other pipe bombs had been found in one of four duffle bags that were "dispersed throughout the front and side of police headquarters."

Around the same time, following attempts to negotiate with the man, snipers used a powerful .50-caliber rifle to disable the van's engine block, then they shot him about half an hour later.

Officers from the Dallas Police Department's specialized SWAT unit fired through the front windshield of the armored van, Brown said.

Police sent in a bomb disposal robot to examine the vehicle and determine whether he was dead. They also carried out a controlled blast to render any explosives in the van inert.

"We can now confirm that the susp in the van is deceased but unable to confirm ID pending Med Ex. identification," Dallas Police Department tweeted, using an abbreviation for medical examiner, or coroner.

Police ramped up security at other law enforcement facilities in Dallas as a precautionary measure after the attack.

A controversial conference turned deadly just last month in nearby Garland, in the same metropolitan area; it featured cartoons depicting the Prophet Muhammad.

Police at the time said two gunmen drove up to the conference centre in Garland where the American Freedom Defense Initiative was organizing a controversial Mohammed cartoon contest, and opened fire with assault rifles, hitting a security guard in the ankle. A Garland police officer then shot and killed both gunmen with his service pistol.
