Mumbai, July 31 - Former union minister Buta Singh's son Sarabjot alias Sweety Singh, who was arrested for allegedly accepting Rs.1 crore bribe, was Friday night sent to police custody till Aug 5 by a city court.

Sarabjot Singh was placed under arrest by the anti-corruption wing of the Central Bureau of Investigation (CBI), which is investigating the case.

Along with Singh, his three associates - Anoop Bedi, Madan Solanki and Dukhsingh Chauhan - were presented before Sessions Judge S.P.H. Nagarkar and remanded to police custody till Aug 5.

Singh had been caught taking a bribe of Rs.10 million from a Nashik-based contractor in return for withdrawing an atrocities case filed against him. He was nabbed in New Delhi late Thursday night and brought to Mumbai.

His three associates were arrested from different parts of India - Mumbai, New Delhi and Pune.

The proceedings in the court of Sessions Judge Nagarkar were delayed by over four hours after at least two of the accused complained that they had been beaten up by the CBI sleuths to extract a confession from them.

Judge Nagarkar ordered that the two be taken to a nearby government medical hospital for a medical examination.

He passed the order for police custody after they returned from a medical check-up around 9 p.m.

The corruption case against Sarabjot Singh involves a complaint filed by a Nashik civic works contractor Ramraj Patil.
