Singh, who is heading the investigation into the case, told mediapersons that CID officials gave a letter two days ago to the district government pleader in Satara about the revision petition.

But the ``confusion'' over the revision petition persisted. ``It (the petition) might have moved by now,'' Singh said. When reporters pointed out that no such application had come up in court today, he said that ``well, it will be moved tomorrow.''

Singh maintained that it was necessary from the investigation point of view to have Udayanraje in police custody. Currently in the Satara civil hospital where he was moved after he complained of chest pain, Udayanraje was remanded to magisterial custody until September 23.Singh also said that the Satara chief judicial magistrate Kamal Vadgaonkar had already directed the Civil Surgeon to submit a report by an experts panel on Udayanraje's health. This was ordered on Tuesday last, he said. No information, however, was available over the action taken by the Civil Surgeon.

Earlier, the defence counsel Rajendra Patil said that investigations would not be obstructed in any manner. ``We have nothing to hide,'' Patil said, reiterating that Udayanraje had been implicated in the case by his political rivals.

Countering Udayanraje's rival Abhaysinhraje's charge that a large number of people were being allowed to meet Udayanraje at the hospital though he continued to be in magisterial custody, Patil said that all visitors were obtaining necessary permission from the sleuths. ``The CID officials are maintaining a list of all visitors,'' he said.

The CID, in the meantime, has detained five to seven persons for questioning. According to M N Singh, the sleuths have recovered some weapons and vehicles used by the assailants. The investigators have picked up ``vital clues'' from the four youths, who allegedly accompanied Udayanraje Bhosale on the night the murder took place.

A tightlipped Singh refused to divulge other details. But he denied that the persons being questioned included two local BJP councillors. Earlier, a senior BJP functionary here told reporters that the police had confiscated vehicles and mobile phone SIM cards belonging to two BJP members of the Satara municipality.

Meanwhile, district collector Anil Diggikar was said to have been summoned to Mumbai. The call from Mumbai came a day after he admitted to reporters that the district administration had been tipped about possible poll violence a week before the Levhe murder.
