A serial sex attacker who raped two teenagers at gunpoint in a cemetery was branded a "danger" to young women by a judge yesterday.

The 26-year-old used his "roguish street charm" to lure his victims into a false sense of security, the Old Bailey heard.

He then turned into a violent monster and threatened them with a gun before attacking them.

The sex beast, who cannot be named for legal reasons, raped two girls, a 17-year-old from Watford, and a 16-year-old, at a cemetery in north London.

His third victim, a 16-year-old with heart problems, was molested in a car park.

He was convicted by a jury of three charges of rape, four of indecent assault and one of attempted rape.
