Olympic medal winning boxer Vijender Singh's name cropped up today after recovery of 26 kg of heroin worth an estimated Rs 130 crore from an NRI's house in Mohali's district and the police said his role was being examined.

Fellow pugilist Ram Singh's involvement was also being probed, police said.

Vijender(27), a DSP rank officer with Haryana police, on his part trashed allegations he has links with an alleged NRI drug dealer arrested by the Punjab Police, saying the "ridiculous charges" would be proved wrong in investigations.

Ludhiana Range DIG M F Faooqui, who also holds charge of Patiala Range, in a statement late tonight said that NRI Anoop Singh Kahlon "made certain disclosures concerning a few sportsmen, including boxers Vijender Singh and Ram Singh, which are presently being examined."

Earlier in the evening at a press conference at Fatehgarh Sahib, 45 km from here, Farooqui had said that during the probe so far it emerged that there was "no direct involvement" of Vijender with the drug peddlers.

Within a few hours of addressing the press conference, Farooqui issue a brief statement.

"Boxer Ram Singh was called by the Fatehgarh Sahib police to join investigation on March 8 but has not been arrested. Investigation is in progress and further details would be given on completion of investigation," the DIG said.

On being contacted by PTI after he had released his statement, Farooqui said "there had been certain disclosures during the investigations and we are examining the statement made by Kahlon. We will carry out further examination as per revelations coming up during interrogation."

Punjab Police late in the evening got the police remand till March 13 of the six accused arrested in connection with the case.

Police had recovered 26 kg of heroin from Kahlon's house in 'Shivalik Vihar' in Zirakpur on the outskirts of the city in Mohali district yesterday. The car of Vijender's wife's Archana was found by police near the NRI's house.

Kahlon and his driver Kulwinder Singh Rockey, arrested earlier, were produced before the judicial magistrate following the expiry of their police remand.

Four others Kuldeep Singh, father of Rockey, Sandeep Singh, brother-in-law of Rockey, Manpreet Singh Gill alias Mani and Gabbar Singh arrested today were also produced before the magistrate.

The police sought a 10 day police remand for the six, but the court allowed their custody till March 13.

Police had sought 10-day remand on the ground that more heroin is to be recovered, but the defence countered saying the police has already made the recovery.

Kahlon told reporters when he was produced in court that he had "relations with Vijender Singh from last 4-5 years" as he (Kahlon) is also a sportsman.

He refused to make any further comments to a volley of questions on Vijender's alleged role in the drug trade.

Police earlier in the day said that during interrogation Kahlon had alleged that Vijender and Ram Singh, a Punjab police inspector, were his "clients" and used to visit him. It said Vijender will be quizzed if required.

Farooqui later clarified that the NRI during his interrogation said that he did not know Vijender directly, but had heard about him through Ram Singh.

However, Kahlon had said that he knew Ram Singh, Farooqui said. Police said that during interrogation Kahlon named a wrestler Jagdish Bhola as the kingpin of the gang.

Enquiries revealed that Bhola was a dismissed DSP of the Punjab Police and stayed in Phase 10 of Mohali.

During a raid at his residence, 10 kg chemical powder, Rs 8.70 lakh cash and some packing material were recovered.

Police said that it had stepped up efforts to nab Bhola who was absconding.
