A state trooper has a broken arm after a hit-and-run on Interstate 85 in Charlotte on Christmas.

According to officials, the incident happened on I-85 northbound near Exit 34, Freedom Drive.

The driver of a white or silver Honda Civic with South Carolina license plates was reportedly going 99 miles per hour when the trooper tried catching up to stop the driver.

Troopers were responding to a call about a mattress in the road at the time of the incident.

The trooper, who has not been named, has a broken right arm but is expected to return to work soon.
