New Delhi, April 23 (IANS): The Congress and the BJP workers on Thursday protested at the Delhi chief minister's official residence and the Delhi Police headquarters in the wake of a farmer committed suicide during a AAP rally here on Wednesday.

Nearly 100 Congress' workers protested outside Kejriwal's Civil Lines home, shouting slogans and waving banners that said the AAP was responsible for Gajendra's death.

"They kept continuing with their speeches even after the suicide," the workers said.

Deputy Commissioner of Police Madhur Verma told IANS that there were nearly 100 protesters.

"They are claiming that it was a conspiracy, and saying that the AAP leaders continued with their 'bhashan' even while the farmer was dying," he said.

After a while, hundreds of the BJP workers marched towards the Delhi Police Headquarters and shouted slogans against the city police.

The police had to use water cannons to keep them away from the main building at the busy ITO crossing, official sources told IANS.

Gajendra Singh, a farmer from Rajasthan who had lost his crops to bad weather, tried to be heard at Kejriwal's famers' rally. But when nobody paid any heed to his pleas, he hanged himself on to a tree, he was sitting at while the rally, organised by the AAP, was on.
