The policemen, holding the rank of Inspector, Sub-Inspector and Assistant Sub-Inspector, were arrested yesterday for their alleged involvement in the killing of Singh here on October 23, 2006, police sources said.

Those arrested are Inspectors Nisar Khan and Naresh Sharma, ASI Surendra Singh, all posted in Jaipur, and SI Satyanarayan Godara, posted in Bikaner, they said.

The case was handed over to the CBI last year following a Supreme Court order.
Dara Singh's family members had alleged that the encounter, which took place in Mansarover area here, was fake.
