Schools are warning parents that Fortnite is making children "aggressive and violent" and fuelling bullying ahead of a new release on Thursday.

A number of primary schools in Gloucestershire have sent out letters to parents and one has held events talking about the effects the game is having on pupils as young as six.

Widden Primary School, in Gloucester, held daily sessions last week telling parents the game was becoming “all consuming” for young children, who risked becoming “addicted”.
