Chatham-Kent police say they have made a fourth arrest after a 14-year-old boy was assaulted off of school property in Chatham earlier this week.
Officers say a fourth male youth from Chatham was arrested on Tuesday and charged with assault.
He has since been released with a future court date in May.
Three other male teens are also set to answer to assault charges in court next month in connection with the case.
Police say the victim was taken to the hospital for medical treatment of undisclosed injuries and later released.
