S.C. Highway Patrol troopers are investigating a collision that sent a North Charleston police officer and a 70-year-old man to the hospital late Thursday.

The wreck happened about 10 p.m. on Dorchester Road, according to Highway Patrol Sgt. Bob Beres.

A 2012 Dodge pickup was headed west on the road when its driver tried to make a left turn onto South Allen Drive. Instead, the pickup crashed into a 2007 North Charleston police cruiser that was traveling in the eastbound lanes, Beres said.

Beres identified the pickup's driver as 70-year-old Nathaniel Wilson of North Charleston. The officer was 37-year-old Keith Fleming, he said.

According to Beres, neither driver was wearing a seat belt when the wreck occurred. They were both transported to Medical University Hospital for treatment.

Wilson was released from the hospital Friday, according to an official. Fleming's condition was unavailable.

The collision is being investigated by the Highway Patrol.

Beres said it was too early to tell if either driver would be cited.
