Samajwadi Party activists on Monday demanded an apology from film star Shahrukh Khan for allegedly abusing Amar Singh at a recent film awards function.

Khan light-heartedly described Amar Singh as a Darinda or fiend at the Filmfare Awards function here. This, however, irked his supporters.

They gathered outside Mannat, Shahrukh's bungalow, and shouted slogans against him.

"During the Filmfare awards function, Shahrukh Khan abused our leader Amar Singh, who is the president of the Uttar Pradesh Vikas Parishad in the most absurd way. We condemn this. We respect him a lot because he has made Uttar Pradesh Uttam Pradesh.

The people of Uttar Pradesh condemn this and ask Shahrukh Khan to say sorry, or else we will come out onto the streets and organize a mass movement against him all over India," said Rama Shanker Tiwari, the President of the Uttar Bhartiya Sangam.

Shah Rukh is reported to have apologized after the function, but according to the Samajwadi Party activists, this was not enough. This led to the police arresting some of them.
