An office-boy of a call centre was arrested on Wednesday for allegedly installing a spy-camera in the ladies' lavatory in the office, police said.

Sanjay was apprehended following investigations into a complaint filed by a call centre in north-west Delhi's Peetampura and its women employees after they found a spy-camera in a packet of freshener.

The incident came to light four days ago but the complaint was made today, a senior police official said.

A case under Section 509 (for using word, gesture or act intended to insult the modesty of woman) of IPC has been registered against Sanjay, working in the administration section of the company.

"When one of the women entered the lavatory they saw something blinking in the odonil packet. On closer scrutiny, she found out that it was a camera and informed the company management," the official said.

The company has about 120 employees and 60 per cent of them are from the North-East states.

According to L Lamak Maram, President of Naga students Union who is helping the victims, the women employees confronted the company management demanding that they be shown the footage.

The company assured it will look into the matter, he claimed, adding, they told the employees that a helper in the organisation was responsible for the installation of camera.

"It is very demeaning and we don't know for how long this has been going on. Some people have seen the footage, which has blurred images of women," an employee said.
