North Charleston police are investigating a report of shots fired on Interstate 26 early Thursday.

Authorities were dispatched to the interstate's Ashley Phosphate exit shortly after 3 a.m., an incident report stated.

A 21-year-old Ladson man told police he was headed westbound in a white 2012 Hyundai Sonata when he saw a gray car quickly approach from a neighboring lane.

Someone fired six or seven shots from that vehicle's front passenger window, according to the report.

The Ladson man lost sight of the suspect vehicle after it exited onto Ashley Phosphate, he told police. He could not provide a description of the occupants, police said.

Authorities located a bullet hole on the Hyundai's front driver's side door and another to the driver's side mirror, police said.

The man told police that before the shooting occurred, he had visited a woman at Bridgeview Village Apartments on Charleston's East Side. The complex was formerly known as Bayside Manor. The man left the complex to search for marijuana, but was unsuccessful, according to the report.

A suspect has not been identified in the shooting, North Charleston Deputy Chief Scott Deckard said.
