US official Raymond David on Lahore murder charge
A US consular employee has been charged with murder after two motorcyclists were shot dead on a busy street in the Pakistani city of Lahore, police say.
Raymond David reportedly said he fired his gun in self-defence because the men were pursuing him in his car.
Another person was run over and killed by a vehicle carrying Mr David's colleagues as they came to his aid, police and witnesses said.
Mr David is expected in court later in the Punjab province capital.
Lahore's police chief, Aslam Tareen, told the BBC Mr David was employed on "security duties" in the consulate.
Protests
He did not have diplomatic immunity and was not one of the foreign security personnel allowed to carry firearms, according to the Pakistani authorities.
Mr Tareen said a Glock pistol had been recovered from Mr David and that pistols had also been found on the two men shot dead.
Mr David said in a statement that the motorcycle rider and his pillion passenger had been trying to hijack his vehicle at gunpoint, according to police.
The US embassy in Islamabad has confirmed the man involved was a consular official but has not specified his role.
The funerals of the three people killed in the incident are expected to take place later on Friday.
More than 100 protesters blocked the road in the aftermath of Thursday's incident, setting tyres ablaze.
Demonstrators later gathered outside the police station where the foreigner's car - a white Honda Civic with a Lahore registration plate - was impounded.
Details of the shooting are still unclear, but a salesman, Mohammad Ramzan, told Dawn newspaper that he had seen a foreigner rushing from a car holding a gun.
"Within seconds he trained his gun at two motorcyclists standing at the Qurtaba Chowk traffic signal and opened fire," Mr Ramzan said.
Police said that the foreigner had used a radio to call colleagues for help immediately after the shooting - and that a second consular car turned up to rescue him.
It is believed the third person killed was run over by the vehicle as it sped to his aid.
The foreigner had tried to flee the scene, but two traffic wardens chased and detained him nearby before handing him over to police, chief traffic officer Ahmad Mobeen told Dawn.
The BBC's Syed Shoaib Hasan in Pakistan says that the incident could worsen anti-American sentiment in Pakistan.
"We want to make sure that a tragedy like this does not affect the strategic partnership that we're building with Pakistan," state department spokesman Philip Crowley told journalists in Washington.
"And we'll work as hard as we can to explain that to the Pakistani people."
