A 22-year-old B Tech student from the Indian Institute of Technology (IIT)-Delhi was arrested in Hyderabad by the cyber crime wing of the CID for allegedly posting obscene photographs of a girl from IIT-Kanpur on a public blog.

The cyber police seized a mobile phone and a computer from the accused, Surender.

The superintendent of police, cyber crime, U Rammohan Rao said they arrested Surender by tracking the Internet Protocol (IP) address of his computer and calls from his mobile phone.

Surender and the girl both hail from Mahabubabad in Warangal district.

Surender came into contact with the girl when she approached him for guidance for IIT Joint Entrance Examinations (JEE). According to police, Surender got attracted towards the girl and tried to take undue advantage of their closeness. When she resisted his advances, he started harassing her through phone calls, SMSs and emails.

A police source said Surender confessed that he bore a grudge against the girl for refusing to marry him.

In order to harass her and her family members, he created a fake profile in the name the girl's sister on a public blog and chatted with people asking them to call her by giving the number of the girl's mother.

The police initiated action following a complaint by the girl's father that Surender was harassing and blackmailing his daughter and other family members.

Earlier, three cases were registered in Kanpur and Mahabubabad against the accused for harassing the girl and trying to forcibly marry her in the Arya Samaj office in Kanpur," Rammohan said.
