Vikas, son of Rajya Sabha MP and Jantantrik Bhahujan Samaj Party (JBSP) leader D P Yadav, was released on bail by a lower court here on Saturday.

"We have reasonable suspicion of his complicity in the crime," standing counsel S S Gandhi submitted before a vacation bench, headed by Justice Mukul Mudgal.

The court adjourned the case to June 7 when police applications for cancellation of bail of three other accused would be taken up.

Gandhi said according to investigations, prime accused Manu Sharma, the son of former Union minister Vinod Sharma, and Yadav were frequent visitors to Bina Ramani's Tamarind Court restaurant where Lal was allegedly shot dead by Sharma on April 30.

The investigation showed further that on the day of the incident, both Sharma and Yadav had gone to Tamarind Court from the house of AmardeepSingh Gill alias Tony, who is charged with destroying evidence in the case.

When the court asked if the charges levelled against Yadav were bailable, and where the ground for cancellation of bail was, Gandhi, citing a Supreme Court ruling, said, "When there is reasonable ground to believe the involvement of an accused in a crime, the bail may not be given."

Police had earlier moved the High Court for cancellation of bail of Tony, Alok Khanna and Amit Jingan, granted by a lower court earlier this month. All three were charged with helping Manu Sharma in fleeing Delhi after the crime and destroying evidence.

Meanwhile, a division bench of the High Court today asked the police to permit the presence of Vikas Yadav's advocate at a "visible distance" in the police station during his interrogation.

The bench, comprising Justices S K Mahajan and Mukul Mudgal, rejected the plea of Yadav's counsel I U Khan that the accused should not be called to the police station at night, saying, "We will not tie theinvestigating officers' hands."

The court made it clear that Yadav's advocate would be present during his questioning at a "visible'', not ``audible distance."

Yadav had moved a petition at the residence of Chief Justice S N Variava yesterday, accusing the police of "harassing" him and applying "third degree" methods against him.

Justices Mahajan and Mudgal, in their interim order yesterday, had allowed Yadav's advocate to be present during his interrogation.
