Delhi Police's Special Cell arrested two men for allegedly planning to open fire outside actor Amitabh Bachchan's residence, police sources said.

One of the accused, Deepak Singh alias Deepak, is suspected to be involved in the murder of Amritsar-based Instagram influencer Mad Sandhu. The other accused was identified as Vikas Thakur alias Vicky, 25, a resident of Jalandhar in Punjab.

Deepak, a resident of Tarn Taran in Punjab, had allegedly planned to stay in Mumbai for an extended period and fire outside Bachchan's residence on the instructions of a gangster based abroad, police sources said.

The alleged plan was linked to a comment Bachchan was claimed to have made on the 1984 anti-Sikh violence. Bachchan has denied making any such comment.

The Special Cell arrested Vikas in Delhi and later arrested Deepak in Mumbai on the basis of information provided by him. Police said Vikas had come from Mumbai to Delhi allegedly to fire at a businessman for extortion.

Mad Sandhu was murdered in Amritsar on October 3. Police alleged that Deepak and his associate, Palwinder alias Kaka, were involved in the attack. Palwinder has already been arrested by Punjab Police.

A case under the Arms Act has been registered and the investigation is underway.
