Internet dangers: 'Never, ever get naked in front of a camera'

The police in Scotland are investigating whether a teenager who took his own life was a victim of online abuse.

Daniel Perry, who was 17 and from Dunfermline, thought he was communicating with a girl his own age in America - but actually he'd been caught up in a scam and was being blackmailed over personal images.

The BBC spoke to internet security specialist Graham Cluley who warned of the dangers surrounding internet web cams and explained the increase in the number of people being blackmailed and victimised online.
