Parents are being advised to change console settings in order to prevent children using their credit cards to buy extra online gaming services.
An 11-year-old from County Antrim ran up charges of over £1000 on his parents' account, spending £448.75 in one day alone.
Computer expert Kevin Curran said parents should set up child accounts to prevent children purchasing any additional gaming extras.
