Vishnu Gupta, the chief of the Hindu Sena, was arrested on Wednesday for allegedly making a false complaint that beef had been served in the Kerala House canteen here.
Gupta was earlier detained and was questioned by Delhi Police.
Delhi Police Commissioner B.S. Bassi had yesterday said that the police was contemplating action against Gupta, under Indian Penal Code (IPC) Section 182 (false information with intent to cause public servant to use his lawful power to the injury of another person).
A major row had erupted earlier this week when Delhi Police entered the premises for an investigation acting on a complaint that beef was allegedly being served at Kerela House.
Kerala Chief Minister Oommen Chandy condemned the "raid" as "highly objectionable".
Gupta, who started as a Rashtriya Swayamsevak Sangh (RSS) worker, said he had also worked for the Bhagat Singh Kranti Sena (BSKS), but left it in 2012.
