'They (police) put him in a jeep and took him deep in the jungle. The 11 bullets we found buried seven inches deep in ground clearly suggest that the policemen laid him down and fired at him from close range.

'While some bullets pierced his body, there were other shots that missed him. There were in all 12 bullet marks on his body. The recovery of the bullets suggest that the shots were fired from three firearms - an assault rifle like an AK-47, a sophisticated 9mm pistol and a pistol of .38 bore,' the official said.

The CBI also found that the pistol recovered from Singh's possession had not been fired.

SIT sources said they had also managed to collect blood samples from the crime scene.

'We have also managed to collect a blood-soaked handkerchief from one of the four police vehicles. We will now conduct a DNA test and if the DNA and blood group matches that of Singh, it will establish beyond any doubt that he was carried in the police vehicle. That would nail the lie of Dehradun police which say that he was trying to flee on a motorbike,' the official added.

The agency's preliminary report was also based on the post-mortem examination carried out on Singh's body that suggested there were 24 physical injury wounds inflicted apart from the bullet injuries.

In addition, the CBI has also dismissed the police claim that Singh and his friends had criminal records.

'So far, we have not found any criminal record either in Ghaziabad or in Meerut,' said the official.

The SIT hopes to finalise its report once the forensic test results come in a fortnight and prepare a chargesheet.
