At least 38 people have been killed and a dozen more injured in northern Haiti on Sunday, when a bus from the private company Blue Sky, drove into pedestrians while fleeing from a separate accident.

The Blue Sky bus line, is a private company offering long-distance routes; an upscale option for travel in Haiti with modern, air-conditioned coaches.

According to witnesses, the driver initially hit two people killing one of them but, out of panic, fled the scene and crashed into a group of musicians who were taking part in a parade about 5 km away. Another 13 people were injured in the crash which took place just before 4 am  in Gonaives, a city of some 300,000 people located about 150 kilometers (90 miles) northwest of the capital Port-au-Prince.

Following the accident, a group of angry crowd tried to attack the driver and burn the bus down.

Authorities initially said they had detained the bus driver, but he had actually fled the scene, Gonaives traffic chief Jeudy Lisate told AFP. Police were still trying to identify him.

In a statement Haitian President Jovenel Moise "expressed his deep sadness following the terrible accident."

"The head of state conveys, on behalf of the whole government, his sincere condolences to the families and those close to the victims,"the statement read.

Moise called for "an investigation as soon as possible to shed light on this tragedy."
