Buta Singh, Chairman of National Commission for SC/ST, mired in a bribery case in which his son was arrested, is still defiant.

He said that he has spoken to Prime Minster Manmohan Singh and briefed him about the political conspiracy.

Buta Singh claims the CBI is using his son Sarobjit Singh to target him and he is ready to answer any question if the CBI interrogates him. Buta Singh categorically said that he will not resign from his post.

Meanwhile, the CBI has got more leads in the bribery case involving Buta Singh's son Sarobjit Singh.

The house of a suspected Bangalore-based hawala operator, Dhuk Singh, was searched by the CBI where some incriminating documents were seized.

He is the third hawala operator the CBI has picked up.

Earlier, the CBI joined by the Enforcement Directorate (ED) to investigate the Hawala trail behind the bribery scandal in which Buta Singh and his son have been implicated.

Meanwhile, Buta Singh, the Chairman of the National Commission for SC and ST, said there is no question of his resigning from the post.

"Why should I resign? I have served the nation for 50 years. I will not run. I will fight," he said.
Buta's son Sarabjot was arrested on charges of accepting a Rs 1 crore bribe from a Nasik-based contractor.

The CBI wants to know what role Buta may have played in the crime and how much he knew of his son's activities?

Buta Singh has been implicated by a key suspect -- Congressman Anup Beghe who has told the CBI that Singh was present at the meeting where the bribe was discussed.

However, in his defence, Sarabjot has claimed that his father knew that Ramarao Patil was trying to bribe him and that Buta Singh had in fact written to the Nashik Police Commissioner complaining about it.

His claims apart, Sarabjot will now have to deal with another case -- of illegally possessing a revolver found when the CBI raided his Delhi residence on Friday.

With the entry of the Enforcement Directorate it's clear that the CBI is following the money trail to build a strong case against Sarabjot and possibly his father as well.
