Jarnail Singh, who hurled shoe at Chidambaram is AAP candidate for LS from West Delhi

After the incident, Singh received several requests from parties to contest, but he declined the offers as he did not want to enter politics then. He was, however, impressed with AAP's slogan of clean politics.

"Arvind Kejriwal joined us in our protest (seeking justice for anti-Sikh riots victims) and assured us that his party would form an SIT to probe the anti-Sikh riot cases if it comes to power," he said.

"I have been associated with the party since May 2013. I have told him (Kejriwal) that I will do any service to the party...Even if it is the job of a watchman," he said.

Singh currently works as a freelance journalist and has authored three books on the anti-Sikh riots and is also working on a documentary. He also works for the victims of the anti-Sikh riots and has been instrumental in getting the children of the victims married.

On campaigning plans, he said his focus would be on Sikh-dominated constituencies in West Delhi.

"There are some three to four Sikh-dominated segments in West Delhi," Singh said, adding that there will be party meetings tomorrow after which the campaigning will start.

The West Delhi constituency has a sizable chunk of Poorvanchali population and is currently represented by Congress leader Mahabal Mishra.
