Members of a right-wing group on May 10 recited the Hanuman Chalisa outside the Qutub Minar complex and staged a protest demanding that the iconic monument in New Delhi be renamed 'Vishnu Stambha'.
At least 30 demonstrators have been detained and taken to a police station, from where they will be released later, a senior officer said.
"They were detained because they cannot protest in the middle of the road causing traffic snarls, thereby creating inconvenience for commuters," the police officer said.
