"Three persons identified as Narinder, Anil and Dharamvir were picked up from a house in Bakshi Mohalla in Jind by a joint team of Delhi and Haryana Police. The Delhi Police team arrived on Thursday," Om Singh Balhara, deputy superintendent of police (Jind) said.
A raid was carried out at the house of Narinder, said Balhara, adding that a Santro car was also recovered during the raid.
The family of Deepak Bhardwaj, has also been through several rounds of interrogation in connection with his murder which took place on March 26. The police believe that 'family dispute and business rivalry' may be the reason for the death.
His sons, Hitesh and Nitesh have been questioned since a lot of Bharadwaj's property is registered in his own name. Sources said that Bharadwaj had not given his family a share in the money.
Bharadwaj was the richest candidate in the 2009 Lok Sabha polls with declared assets of over Rs 600 crore.
