A man shouted slogans on Saturday as Prime Minister Manmohan Singh got up to deliver his address at an international conference in New Delhi.
"Prime Minister go back," the man shouted at Singh as he walked up to the rostrum to deliver his address 'Conference on Economic Growth in Asia and Changes of Corporate Environment'.
The Prime Minister waited for a while at the rostrum as security officials took the lone protestor out of the plenary hall of Vigyan Bhawan.
Police officials said the protester has been detained for questioning.
The conference, organised by Indian Law Institute, was attended by legal luminaries from across Asia besides Chief Justice of India S H Kapadia and Law Minister Salman Khurshid.
