Uma Khurana, a teacher in the Government Sarvodaya Kanya Vidyalaya at Aruna Asaf Ali Marg in New Delhi, has been arrested by Delhi Police after she was allegedly found to be running a sex racket.

A sting operation by a Hindi news channel had shown Khurana running the sex racket. The channel allegedly exposed how the teacher forced students into prostitution and pornography. Following the report, an angry mob gathered on Asaf Ali Marg, outside the school.

The school suspended the teacher after parents and locals gathered outside the school and also torched a police vehicle. Nine persons including two policemen and the local councillor were injured in the clash outside the school as the parents demanded action against the teacher.

Police had to resort to tear gas shelling to control the mob and Rapid Action Force was also deployed to bring the situation under control.

The Deputy Speaker of Delhi Assembly said that it was natural that the parents would react violently to the report. He has appealed for calm.

The Delhi Police on Friday arrested the reporter of the television news channel in connection with a fake sting operation, showing a mathematics teacher allegedly forcing schoolgirls into prostitution.

"We have arrested Prakash Singh, reporter of Live India channel, for carrying out a fake sting operation, which showed that Uma Khurana, mathematics teacher of Sarvodaya Kanya Vidyalaya, was forcing her students into prostitution," a senior police official told IANS.

"We are currently interrogating him and it seems that he conducted the sting to ensnare Khurana, who had some financial disputes with his friend Virender Arora," the official added.

The official said that Prakash Singh also hired Rashmi Singh, a freelance journalist who writes for a Hindi newspaper, to act as victim in the sting operation. She was reportedly part of the conspiracy to frame Khurana.

Police had arrested Rashmi Singh late Thursday. She has been charged with cheating, fabrication of evidence and criminal conspiracy and was produced in court Friday afternoon.

Khurana was arrested last week after the channel telecast the sting operation purportedly showing that she was running a syndicate making pornographic films, featuring her present and former students.
