The concerned mother said: 'Parents need to be more vigilant and aware of what their children are doing on social media. 'I have recently been shown screenshots of a video of two 13-year olds in Plymouth having sex which was added to their Snapchat story. 'This was broadcast to their hundreds of followers, probably all other children the same age. Two people in hospital after car and van crash leaves A388 blocked in Cornwall.'I know for a fact that this has been seen by many children all over Plymouth as the two children in question have hundreds of Snapchat followers.' The mum added: 'This is a serious welfare issue, not to mention illegal and really very dangerous. 'It’s obviously completely inappropriate for them to be doing and then to broadcast it on Snapchat is disgraceful. A secret look at what lies beneath Truro’s Lemon Quay.'Not to mention that this kind of thing could easily get into the wrong hands.
