Mumbai/IBNS: The Mumbai Police has initiated the extradition process to bring back Anmol Bishnoi, the brother of gangster Lawrence Bishnoi, whose gang has claimed responsibility for the firing outside Bollywood superstar Salman Khan's house and killing Nationalist Congress Party leader Baba Siddique, media reports said.

Police sources, as NDTV reported, said a special court for cases related to the Maharashtra Control of Organised Crime Act (MCOCA) issued a non-bailable warrant against Anmol Bishnoi.

Police began the extradition process after the United States alerted about his presence in the country.

The National Investigation Agency added Anmol's name in the most-wanted list last month.

A reward worth Rs. 10 lakh was also announced for Anmol's arrest.

After Siddique's murder, one of the Bishnoi gang members shared a post on Facebook where he hinted at Siddique's close ties with Salman and links to underworld people that cost him his life.

On the night of April 14, gunfire shook Mumbai's Bandra neighbourhood when two men on motorbikes fired multiple rounds outside Salman Khan's residence.

The attackers, linked to the Lawrence Bishnoi gang, were charged with conspiracy to murder and other serious crimes.

The Bishnoi gang is operating with 700 shooters from five states with an outreach outside India as well.

Bishnoi, who is in jail, operates from prison using mobile phones. He is switched from one prison to the other. First jailed in 2012, he is now in Ahmedabad's Sabarmati Jail where he was shifted from Delhi's Tihar Jail last year in August.

Why is Lawrence Bishnoi targeting Salman Khan?

Lawrence Bishnoi, who is now lodged in Sabarmati jail, was just five when Salman Khan allegedly hunted down two endangered blackbucks along with his co-stars during a film shoot in Jodhpur in 1998.

In the same year, members from the Bishnoi community had filed a case against Salman and his co-stars from the film, Hum Saath Saath Hain. 

Twenty-six years later, the threat on Salman's life looms large as Bishnoi, who was a kid in 1998, is now running a gang which has a team of about 700 shooters with the rage over the allegedly killing of blackbucks on.
