Yadav was summoned to Mehrauli Police Station in south Delhi at 10:30 am by a police team headed by Additional Deputy Commissioner of Police Vivek Gogia and was grilled till 2 pm find out the whereabouts of Vikas.

Vikas, ``absconding'' since the model was shot dead in socialite Bina Ramani's `Tamarind Court' restaurant on April 30, is being sought by the police, along with Ravinder alias Titu for their alleged role in helping main accused Manu Sharma, the son of Chandigarh Congress leader Vinod Sharma.

According to the police, Vikas and Titu had helped Manu in hiding the weapon of offence (a .22 bore pistol) after he allegedly shot at Jessica for refusing to give him drinks at the restaurant.

After questioning Yadav, Gogia said, ``He has given some information about Vikas which is beingverified.''

``We have sought some information from him about Vikas' whereabouts, which he has given to us today. We will take follow up action on the basis of the information,'' he said.

Gogia admitted that Yadav had been avoiding the police and ``we were contemplating to take action (sic) against him if he had not appeared before us.''

He said police parties sent to various places were not able, so far, to trace either Vikas or Titu.

Manu Sharma was yesterday taken to Chandigarh by a police team to recover the pistol allegedly used in the killing of the model.

The police yesterday had said that the team would also verify certain statements made by Manu during the interrogation.

The police team is expected to explore the possibility of framing charges against those who allegedly provided shelter to Manu before he surrendered to the authorities, they had said.

Police said the recovery of the 0.22 bore pistol, allegedly used by Manu in shooting down the model, was of paramount importance forprosecuting him. Manu's police remand expires tomorrow.

Later, addressing a press conference at his residence, D P Yadav accused the police of conducting a "shoddy probe" in the case and demanded that it be handed over to the Central Bureau of Investigation (CBI).

He also alleged that a "political conspiracy" was behind the naming of his son Vikas in the case. ``The police is bent upon protecting influential people like Bina Ramani, owner of the illegal South Delhi bar,'' he said.

"My son is innocent. When he was not at the illegal bar on April 30 when the murder took place, how could he be involved in it (the case)?" Yadav said, and added, the "police can't make out a case against Vikas just because he knew Manu, the prime suspect in the case."

The Jantantrik BSP leader also condemned the repeated police statement that he had gone underground after he was summoned to the police station for questioning with regard to Vikas' whereabouts. "On May 8, I had sent a letter to the Station House Officer ofMehrauli police station requesting him to grant me two days' time to present myself before the police due to political engagements," Yadav said, releasing a copy of the letter to the Press.

Yadav said he had never shied away from the police, adding he was cooperating with the police and would continue to do so.

Yadav maintained that Vikas had not got in touch with him since May 3. He said he would ask Vikas to present himself before the police as and when he was able to establish contact with him.
