Thirty-year-old Derek Alan Younger of Cumberland is under arrest, following a stabbing incident early Sunday evening in the 200-block of Arch Street. Several people were involved in an argument, which turned into a physical confrontation, and the suspect left in a vehicle driven by another person. The stabbing victim was treated at UPMC-Western Maryland. The driver returned to police headquarters to speak with investigators, and an arrest warrant was issued for Younger, who turned himself in to police.  He was charged with attempted second-degree murder, first and second-degree assault, and other related charges. He had been held without bond, pending his next court appearance. The investigation is continuing by Cumberland City Police and the C3I Unit.
