The father of the girl, has approached the Cyber Cell of Delhi Police's Economic Offences Wing after the family began receiving vulgar calls. The girl is a student of a South Delhi school.

The web page describes the teenager as a "sex teacher" and has obscene photographs and contact details such as her home address and telephone numbers, police said.

This is the second incident that has come to light about Orkut misuse in Delhi in less than three weeks. Earlier in February, an air-hostess had moved a court here alleging that someone has opened an account in her name on Orkut wherein she is being described as a "sex struck woman".

The teenager's family had received the first call almost a month ago where the caller wanted to speak to the girl. Similar calls poured in later, the police said, adding all the callers referred to Orkut.

The family had a harrowing time when two strangers knocked at their door a fortnight ago and told them the girl had invited them for sex through Internet, they added. Police said a case has been registered and investigations were on.
