NEW ORLEANS, Sept. 4 - New Orleans police officers yesterday shot and killed four people and wounded two others who had fired at officers escorting a convoy of contractors across a bridge, the authorities said.
The group of 14 contractors from Boh Brothers Construction, one of New Orleans's largest construction companies, was working for the Army Corps of Engineers on levee repairs and drainage, said Robert Boh, the president of the company.
The convoy, which included officials from the Army Corps of Engineers and was being escorted by a group of police officers on an anti-looting detail, was crossing the Danziger Bridge, 10 miles northeast of the French Quarter, when the shots were fired.
W. J. Riley, the assistant superintendent of police in New Orleans, said a gunfight ensued between the police and a group of six men.
"All our officers said the assailants all had guns," Mr. Riley said. Later, he said all the assailants were "neighborhood thugs."
"Five of the subjects were shot," he said. "Two were killed, three were wounded." The sixth gunman was arrested and charged with attempted murder of a police officer, but none of the gunmen were identified.
The superintendent said that as the shooting broke out, two of the men fled across the bridge and were pursued by officers.
"One officer saw one subject go into a building," he said. "Another ran around the building. Shots were fired." Mr. Riley said one of the two was killed and the other was arrested.
None of the contractors were hurt and they were even initially unaware that anyone had been shot, said Mr. Boh, learning of it only later in news reports on the Internet.
