Namdhari, an aide of Ponty, was arrested on charges of murder while seven others were arrested on charges of trespass, kidnapping and dacoity. Tyagi, 27, is charged with criminal conspiracy and other related sections. "We have arrested Sachin Tyagi, a gunman Constable of Uttarakhand Police for his role in conspiracy that led to the murder of Hardeep Chadha," SBS Tyagi, Deputy Commissioner of Police (Crime), said.
He said that during investigations it emerged that Tyagi had unauthorisedly arrived in Delhi along with Namdhari and used his official weapon in an unauthorised manner and fired at Hardeep. Namdhari himself was in possession of 0.30 bore pistol but did not possess valid licence for bringing the weapon to Delhi, he said. Tyagi joined as a constable in Uttarakhand Police in 2005 and was attached with Namdhari as his PSO since Jan 2012.
Delhi Police had alleged Namdhari had also opened fire at Ponty's brother Hardeep during the shootout at Chattarpur on Nov 17 in which both the brothers were killed. Namdhari had said he did not fire at Hardeep. A senior police official said they were investigating all angles including whether Namdhari fired at Hardeep resulting in his death. "We are not leaving any angle," the official said.
Asked about Tyagi's role, he said the PSO allegedly made false statements before investigators and helped in destroying evidence. The official claimed that Namdhari allegedly handed over to Tyagi the gun he used to open fire at Hardeep. "Tyagi handed over the firearm to one Sonu who in turn gave it to Satnam. Tyagi knew this was an important evidence but he helped Namdhari," the official said.
