New Delhi: Agitated parents and locals went on a rampage outside a city school today following a TV channel expose which purportedly showed a lady teacher blackmailing girls after filming them in compromising position.

Parents and locals gathered in front of Delhi government- run Sarvodaya Kanya Vidyalaya on Asaf Ali Road this morning after the channel aired the sting operation. The protestors set ablaze two vehicles, damaged a number of other vehicles and public property and pelted stones at police personnel before being lathicharged, a senior police official said.

The expose purportedly showed the victims telling the TV reporter that a Mathematics teacher had allegedly filmed them in compromising position and was forcing them into prostitution. The girls claimed that the teacher, Uma Khurana, blackmailed them by threatening to pass on the CDs to their parents if they did not cooperate with her.

The Delhi government suspended the teacher immediately after the TV expose and ordered an enquiry into the matter, an official said.
