Mumbai: An unidentified organisation Jaish-ul-Hind has taken responsibility for placing the explosives-laden van outside Reliance Industries Head, Mukesh Ambani's house Antilia in Mumbai.

In a viral message on the Telegram app, Jaish-ul-Hind claimed that the explosive-laden van outside Ambani's house was 'only a trailer" and 'a big picture is yet to come'.

Jaish's message on Telegram read, "The brother who placed the SUV near the Ambani house has reached the safe house. This was just a trailer and big picture is yet to come." The organisation has demanded money through Bitcoin. In the letter they have challenged investigative agencies saying, 'stop us if you can'.

Jaish is the same organisation who claimed responsibility for the blast outside Israel Embassy in Delhi last month.

On Thursday, a van with explosives inside was found parked near Antilia in South Mumbai. An FIR has already been registered in the case. A threatening letter addressed to Mukesh Ambani and his wife Nita Ambani was also recovered from the van found outside their residence. The letter said that gelatin sticks and the van outside his residence were just a "trailer".

Taking note of the incident, Mumbai police crime branch has deployed 12 teams to investigate the matter. Ambani and his family are already under Z plus category protection.
