Despite having Sukhdev Singh Namdhari in custody for eight days, the Delhi Police have failed to nab the man who changed the numerical code of his gun to confuse the investigators.
Identified as Jahangir, the gun expert had allegedly changed the numerical code of Namdhari's .30 bore gun after the shootout at the Chattarpur farmhouse in which Ponty Chadha and his brother Hardeep Singh were killed.
Sources said the gun reached Uttarakhand through a relative of Namdhari and the sacked Uttarakhand official's son got the numerical code changed by Jahangir, who has a shop in Rampur, Uttarakhand.
"The ballistic report of the bullet found at the crime scene and the gun recovered from Namdhari will not match now. To connect the link, the arrest of Mistri is crucial. He is currently hiding in Punjab and we will take Namdhari to his possible hideouts," a senior police officer said.
Apart from Mistri, five more associates of Namdhari —Hardayal Singh, Simranjeet Singh, Jasbir Singh, Balkar Singh and Baaj Singh — are also untraceable. Police said a vehicle present at the time of shootout also needs to be recovered. The police are also looking for Namdhari's son.
Raids have been conducted in Gadarpur, Rudrapur and other cities but police are yet to trace him.
Official said that during the initial days of investigation, the south district police allowed Namdhari to leave the capital and this gave him time to tamper with the evidence.
Also, Uttarakhand Police had seized two guns from Namdhari's residence immediately after the shootout, but the third gun was recovered a week later.
"He has three licensed guns, of which two were seized by Uttarakhand police and one by us. Most likely, he fired from the gun that was recovered last," he added.
Experts say that every gun has a unique numerical code and from the records of the licensing authority and reports of ballistic experts, it can be matched with the the bullets that were fired from it. It will help police nail Namdhari.
