One of the two men seen in a CCTV footage opening fire outside Bollywood superstar Salman Khan's house in Mumbai is suspected to be from Gurugram, sources in the Delhi Police said on Sunday.

Two men fired four rounds outside Bandra's Galaxy Apartments, where the actor resides, around 5 am and fled. According to a Bandra police official, an FIR has been registered against "unidentified persons" under IPC section 307 (attempt to murder) and the Arms Act.

An official source in the Delhi Police said one of the two is suspected to be a criminal from Gurugram who was involved in multiple killings and robberies in Haryana and is wanted in the murder of Gurugram-based businessman Sachin Munjal in March.

Gangster Rohit Godara, who is based abroad, had in a purported social media post claimed responsibility for Munjal's murder. He is a close associate of gangsters Lawrence Bishnoi, his brother Anmol and Goldy Brar.

Hours after the firing outside Salman Khan's house on Sunday, Anmol Bishnoi, in a purported online post, took responsibility for the incident and issued a warning to the Bollywood actor, saying it was a "trailer", police sources said.

In March last year, an e-mail threatening Khan was received at his office following which the Mumbai Police registered an FIR against Lawrence Bishnoi and Goldy Brar and another person under IPC sections 120-B (criminal conspiracy), 506-II (criminal intimidation) and 34 (common intention).

The FIR was based on a complaint lodged with the Bandra police by one Prashant Gunjalkar, who according to police frequently visited the Bandra-based residence of Khan and ran an artist management company.

The e-mail stated that Khan must have seen an interview given to a news channel by Lawrence Bishnoi, and if not, he should see it. Addressing Gunjalkar, it said if Khan wants to close the matter, he should talk face-to-face with "Goldy bhai", adding “there is still time but agli bar, jhatka dekhne ko milega” (you'll see something shocking next time), Mumbai police earlier said.

In June 2022, an unidentified person threatened Khan via a handwritten note, they said.
