Ranchi, Feb. 24: Students in schools are continuing to bring mobile phones to classrooms, flouting with impunity the ban imposed on the gadgets after the sleaze video scandal erupted in Delhi.

A girl in Class XI at Delhi Public School (DPS) has complained to authorities against a classmate, who, she alleged, was trying to ?photograph? her on a mobile phone that had an in-built camera.

The boy?s handset was seized but the school said it did not have a camera as alleged by the girl.

?When the girl complained to me that she had been photographed by the boy, I asked her to go and sit quietly in the class. Later I went to the class and told the boy to hand me over the mobile. He handed me over a mobile with zero balance. This does not even have a camera,? said Prathiba Choudhary, the school?s physical education teacher.

The boy has admitted in a letter to the authorities that he had a mobile phone, but without a camera, with him, but says he was only ?pretending? to film the girls near the engineering drawing section on Tuesday.

As punishment, the boy has been told not to come for a week. The boy?s father met the principal today.

The extent to which mobile phones equipped with a camera can be misused became apparent last November when a student of DPS, RK Puram, in New Delhi, had filmed his girlfriend in a compromising position.

The accused, a Class XI student, had sent the MMS (Multimedia Messaging Service) of the two-minute video clip to his friends. The clip soon hit the internet websites and the video CD markets. Investigations by Delhi police led to the arrest of three persons, among them an IIT student who had sold the clip on the internet.

Most schools in Ranchi clamped a ban on the use of cellphones after the scandal hit the headlines. But authorities admitted that keeping a check on all of them is an uphill task.

DPS principal Mahesh Bareja said with 4,000 students, it was difficult to find out who was carrying a mobile phone.

But the incident has forced him to crack the whip. ?From the next session, the entry form of Delhi Public School (DPS) will carry a special column under which a parent has to sign that a child coming to school will not be allowed to bring a mobile phone with a camera,? Bareja said.

Officer-in-charge of Jagannathpur police station Dileep Kumar Barma said: ?We can do nothing if the girl?s parents do not come out openly against the accused.?
