Teams of Bihar police and Siliguri Metropolitan Police jointly on Saturday night nabbed a youth who is the main accused in the murder of the former mayor of Bihar’s Katihar town.

Last Thursday, Shivraj Paswan, who was the mayor of Katihar Municipal Corporation till June-end, was gunned down at Santoshi Chowk area of the town. A case was filed with the Town police in Katihar. Police had nabbed four persons.

However, Bihar police sources said the name of Saket Shubham, in his late 20s, came up as a principal suspect.

“During investigation, the Bihar police came to know that Saket had fled to Siliguri. Accordingly, they reached here and along with the local police, arrested him from a house in Milanpally (ward 26),” said Sushanta Neogi, a government lawyer in Siliguri.

Saket, police sources said, was hiding at a relative’s place.

On Sunday, Saket was produced at a local court.

“We have filed a petition for his transit remand. The Bihar police want to take him to Katihar for further investigation,” added Neogi.

Paswan’s brother, who had filed a complaint, had also named the nephew of the BJP MLA of Katihar as one of those involved in the murder.
