Police spokesman Steven Berry says the stabbing happened early Saturday. Police responded to the rail station near Sycamore Drive and Main Street after getting reports of screams coming from the bathroom.
When they arrived, they found the cab driver suffering from multiple stab wounds. He died from his injuries after being taken to a local hospital. His name has not been released.
Detectives say they have a man in custody after witness provided a description of a man who was apparently seen walking away from the area. They say it doesn't appear the suspect was a passenger in the cab.
