Police, investigating the alleged killing of a Dhanbad judge,arrested the husband of the owner of the autorickshaw that was used to run him over late on Saturday, and conducted searches across 50 locations in Dhanbad district till Sunday morning during which time officers questioned over 200 people.

Ramdev Verma, the husband of the auto owner Saguni Devi, lodged a false FIR at Patherdih police station, alleging that his auto was stolen on July 27, the day before judge Uttam Anand was hit with the auto while he was on his mornoing walk, leading to his death in hospital. The false FIR, filed to seek insurance claims, came to light after the regular driver of the auto, Gopal Lohar, was arrested and taken into police custody on July 30.

A special investigation team is probing the death of the judge that the Supreme Court says "constitues the larger issue of safety and security of judicial officers in the country". Chief minister Hemant Soren recommended a CBI probe into the alleged killing on Saturday.

ADJ (operations) Sanjay Anand Latkar, who is heading the state-level SIT team, is camping in Dhanbad to supervise the probe. The police,that had on Thursday arrested two youths alleging one of them was driving the auto when it hit the judge, took the auto’s regular driver Gopal Lohar into custody for questioning on Friday.

So far, the police have refused to divulge details of their findings. But sources claimed that the duo, Lakhan Verma and his accomplice Rahul Verma, had told police that the judge's death was an accident since they were drunk and could not control the vehicle when it hit Anand.

On Sunday, ADJ Latkar and his team inspected the site of the incident once again with a large number of policemen, including City SP R Ramkumar. He also took stock of CCTV camera placements at the site and at the nearby intersection.
