A man armed with a knife walked into the Exxon On The Run service station, on Idlewild Road, about 3 a.m. Thursday and took the clerk's car keys, Stallings police say.
The robber took the clerk's car and fled north on nearby Interstate 485.
Stallings Police Officer J.V. McHan found the stolen vehicle farther north on the interstate, and the suspect jumped and ran. Law enforcement officers tried to catch the suspect but failed.
A short time later Stallings Police Sgt. T. L. Harrington saw a man matching the suspect's description, also near I-485. The man fled in a nearby wooded area. Union County Sheriff's deputies, police officers from Matthews and Mint Hill, and N.C. Highway patrol officers assisted in the search. However, no one has been arrested.
If you have information, contact the Stallings Police Department at 704-821-0300, or the Union County Crime Stoppers at 704-283-5600.
