"How long people will tolerate? But if something like this (defacement of walls) has happened, I apologise for that. The slogans (written on walls) were inappropriate. We should think before taking any such step as people are watching our agitation," he told reporters.
Scores of Team Anna supporters protested outside the 7 Race Course Road residence of the Prime Minister and threw coal pieces into the premises besides defacing walls.
In a letter to Team Anna, police said around 100 supporters had protested outside the Prime Minister's residence, staged a snap demonstration and threw water bottles, lumps of coal, currency notes and coins inside the premises. "They were very aggressive and was removed from there only after great difficulty," the letter said requesting Team Anna members not to make any provocative speeches.
