The teenager was attacked with a screwdriver.
Madang Police Commander Acting Superintendent Mazuc Rubiang said young boys acting as thugs are using offensive weapons such as screwdrivers and kitchen knives to attack people and steal from them.
Rubiang thanked the police officers who rescued the boy and brought him to Modilon General Hospital. He added that others have not been so fortunate, and have lost their lives because they did not get medical help quickly.
