If your child is playing 18-rated games such as Call of Duty and Grand Theft Auto, you could be reported to the police and social services. That's the message being sent to parents by a group of primary and secondary schools in Cheshire. In a letter, the Nantwich Education Partnership has warned parents about the levels of violence and sexual content that are prevalent in mature games. It says regular exposure could lead to "early sexualised behaviour" and leave children "vulnerable to sexual exploitation or extreme violence." Some parents have already voiced their disapproval, but headteachers say they're merely following the guidance set by their local authority: "If your child is allowed to have inappropriate access to any game or associated product that is designated 18+, we are advised to contact the police and children's social care as this is deemed neglectful."
