Jamalpur police nabbed an undergraduate student on Monday evening for allegedly posting pictures of a schoolgirl with an objectionable message on a social networking website.

The arrested Vikash Kumar (18) is the son of a homeguard jawan and a resident of Heru village under the jurisdiction of Kasim Bazaar police station in the district.

The FIR lodged by the minor's mother, a resident of Jamalpur town, said the accused approached the girl. "Vikash tried to get close to the minor but failed to do so. So he procured her mobile number and a photograph somehow. Thereafter, Vikash posted her picture on Facebook with a message: 'I am a call girl. I need customers. Call me on the mobile number given here'," said Rajiv Kumar, station house officer, Jamalpur police station, on Tuesday.

"The girl started get calls without a break. Her entire family had to undergo a harrowing experience. Then, the minor's mother approached the police. We swiftly took the culprit in custody and sent him to jail," the SHO said.

Jamalpur police have lodged an FIR against the culprit under Section 67 of the Information Technology Act, 2000, and other related acts, police said. Section 67 has the provision of imprisonment up to five years with a fine extending up to Rs 1 lakh on the first conviction.

"In wake of growing incidents of cyber crimes against women in the district, Munger police have decided to organise a weeklong workshop on women's empowerment in schools and colleges of Munger town in the first phase to embolden girls and women to counter the menace of cyber criminals. I have directed all SHOs of police stations in the district to act swiftly in cyber crime cases, particularly relating to women," said Munger superintendent of police Aashish Bharati.
