At least four people were killed and 15 others injured after a matatu reportedly lost control and overturned along Enterprise Road in Nairobi on Wednesday night, police said.

There are concerns the number of casualties could rise, police said.

Police said the incident happened at about 8:00 p.m. on June 3, near the Dar es Salaam Roundabout in the Industrial Area.

According to police, the vehicle was heading from the DT Dobie direction towards General Motors when a motorcycle, whose rider has not yet been identified, is said to have emerged from Dakar Road and did not give way.

Police said that in an effort to avoid a collision, the driver swerved, hit the central island kerb at the roundabout, lost control and the vehicle overturned onto its left side.

The motorcycle rider is said to have left the scene immediately after the incident.

The driver sustained a fracture on the left leg and was taken to hospital for treatment.

Four people died at the scene from multiple injuries. They included three passengers and an unidentified female pedestrian estimated to be about 30 years old.

At least 15 other passengers on board sustained injuries of varying severity and were taken to different hospitals for treatment.

Police officers visited the scene and launched investigations into the circumstances surrounding the crash.

The bodies of the deceased were moved to the Nairobi City Mortuary pending identification and post-mortem examinations.

Authorities are also seeking to trace the motorcycle rider believed to have been involved in events leading up to the accident.
