Meanwhile, following the protest, policemen were deployed at Tejpal's Jangpura residence in south Delhi.
"Arrangements have been made to prevent any kind of chaos outside the office. Policemen have also been deployed outside his residence," a police officer said.
A case of sexual assault was registered against Tejpal in Goa on Friday. The Goa Police have said a Crime Branch team will be sent to Delhi.
Tejpal is accused of sexually assaulting a junior woman colleague in a five-star hotel in Goa earlier this month.
"We will cooperate in the investigation. However, they (Goa Police team) have not yet reached Delhi," special commissioner of police (law and order) Deepak Mishra said.
According to sources, the Goa Police team may reach Delhi by Friday night. They will question Tejpal and also collect letters exchanged between Tehelka managing editor Shoma Chaudhury and the victim girl.
