New Delhi, Aug 2 - Former home minister Buta Singh Sunday accused the Central Bureau of Investigation (CBI) of 'victimising' him and his son Sarabjot alias Sweety Singh, who was arrested for allegedly accepting a Rs.1 crore bribe. He, however, said he was ready to cooperate in the probe.

'The CBI is corroborating with the complainant and is not playing the role of an investigating agency. I and my son are being victimised,' Buta Singh told reporters at a press conference here.

'I am ready to cooperate with the investigation at any level but it should come through a proper designated channel,' he said.

The former union minister, who is now chairman of the National Commission for Scheduled Castes/Scheduled Tribes, also claimed that he was being politically targeted, but refused to name any political party.

'I will reveal this when the right time comes,' Buta Singh said.

His son Sweety Singh was arrested Friday on charges of accepting Rs.1 crore bribe - the first lot of the Rs.3 crore (Rs.30 million) that he had allegedly demanded from Nashik-based contractor Ramraj Patil to have a case against him withdrawn by the Scheduled Castes/Scheduled Tribes commission that Buta Singh heads.

Sweety Singh has been remanded to police custody by a Mumbai court till Aug 5.

Buta Singh said he had informed Prime Minister Manmohan Singh about the case and he would seek time to meet him.

'The prime minister responded positively to my worries and asked me to brief him about the details related to the case,' he said.

Expressing his loyalty to the Congress Party, he added: 'I have full faith in the Congress party and my decision of fighting the Lok Sabha elections independently was not within the party code of conduct and I am regretting the same.
