SALISBURY – Police have arrested the man they say is responsible for stabbing 20-year-old Matthew Morris at Lancaster’s Car Wash last week.
According to police, Morris and a juvenile, were vacuuming the car when a blue minivan with a white male driver and five black males with dreadlocks pulled up next to them.
Police said one of the men punched Morris in the face, and as Morris was in a seated position in his car, others stabbed him in the stomach with an 8-inch knife and robbed him. 
Samuel Caldwell, IV, 20, of 926 E. Lafayette St., has been charged with two counts of robbery with a firearm or other dangerous weapon and assault with a deadly weapon inflicting serious injuries. He is in jail under a $50,000 bond.
Salisbury Police said Morris knew who Caldwell was the night he was stabbed, and through the investigation, Caldwell was named as the suspect. Caldwell was seen walking down Lafayette Street Tuesday afternoon and arrested.
Police anticipate charges for others that were involved in the robbery.
Morris was transported from Rowan Regional Medical Center to Presbyterian Hospital in Charlotte after the stabbing. Morris was initially admitted to the intensive care unit, but his condition has improved. Morris has since been released from the hospital.
