Saucy snaps of two teachers at a Croydon Catholic school have spread like wildfire among its pupils.

Explicit pictures of Kiran Sohanpaul, a teacher at St Joseph's College in Beulah Hill, Upper Norwood, have been passed around classes after being found by a pupil on her mobile phone.

The boy found the nude pictures after the teacher lent him her phone to listen to a song.

The picture apparently shows the 39-year-old lying naked on a bed.

Astonished pupils also found a full-frontal photo of the sixth-form deputy head Peter Cook.

The photo of the 38-year-old dad-of-two, who is believed to have a long-term partner, shows him naked and is thought to have been taken on a school trip.

A spokesman for the 150-year-old specialist maths and computing school, said: "The college is presently investigating the situation. The matter will be dealt with through the college's normal procedures."

According to the school's sixth-form prospectus it "provides an ethos grounded in the teaching of the Catholic Church".
