Police are working to identify the driver of a vehicle after it struck a pedestrian Sunday night in Mount Pleasant.

The hit-and-run occurred on Longpoint Road near Needlerush Parkway at around 11:30 p.m., according to police.

A witness told authorities she and another man were in a car traveling on Long Point Road when they saw a white car behind them weaving back and forth and almost striking another car, according to an incident report.

When the vehicle stopped at a traffic circle, the pair wanted to check on the vehicle, so one of them approached the car, the report stated.

The driver backed the car up then accelerated, hitting the man and then drove off into the Longpoint subdivision, according to the report.

The man who was hit was transported to Medical University Hospital and suffered a fracture, police said.

Authorities described the vehicle as a four-door, white Nissan sedan.

The car may be missing the front hood ornament and may have damage to the front area of the vehicle, police said.

Authorities are asking anyone with information to contact police at 843-743-7200.
