Lucknow, Feb 27 (IANS): A Samajwadi Party (SP) leader and a former legislator Rakesh Singh has been arrested after a smuggled pistol was seized from his house in Aligarh, police said on Tuesday.

The former lawmaker has been booked under the Arms Act. He has been taken for interrogation to the Quwarsi police station, the official said.

A team of the Special Task Force (STF) of the Uttar Pradesh Police raided the former MLA's house from Charra in Mathura around midnight.

The STF official said that the operation was based on a "conclusive lead" given by a gun racket runner, who told the team that he had sold a smuggled weapon to the former legislator.

The recovered pistol is a 9mm sophisticated 'Tauraus' made in the US, Inspector General (IG) STF Amitabh Yash told IANS, adding, "We are trying to dig deep into the issue."

Yash also added that since the investigation was underway more information could not be shared with the media.

The Tauraus pistol is said to be priced anywhere between Rs 4.5 lakh-5 lakh.
