Police detained over 300 "anti-social elements" in the city's Northern Districts to prevent any untoward incident during Clinton's visit to Mahatma Gandhi's Samadhi at Rajghat, Joint Commissioner of Police Suresh Roy told PTI.

Two activists of CPI(ML) Red Flag were arrested while pasting anti-Clinton posters. They were later let off, police sources said.

The entire route from Maurya Sheraton Hotel to the places the US President is scheduled to visit tomorrow, including Parliament House, Hyderabad House, Rashtrapati Bhavan, Ashoka Hotel and Rajghat were thoroughly sanitised by anti-sabotage teams. Police presence all along these routes have been further strengthened as a precautionary measure.

Though Clinton left early in the morning for Bangladesh for a day-long visit and his daughter Chelsea and mother-in-law Dorothy Rodham went to Jodhpur to celebrate Holi, security in and around the Maurya hotel, where the Presidential entourage is putting up, remained tight.

Activists of CPI(ML) New Democracy paraded Clinton's effigy through several industrial areas in the city and set them afire protesting against "US imperialism".

Noted social activist and Arya Samaj leader Swami Agnivesh would be sitting on a fast from tomorrow in protest against the visit.
