Police have tightened security around Industrial Mukesh Ambani's residence and office following a threatening letter allegedly from the Indian Mujahideen (IM), reported The Times of India.
The handwritten letter addressed to Ambani warned of dire consequences for his investment in Gujarat and his undue support to State Chief Minister Narendra Modi.
The Reliance Industries chairman was also accused of seizing land of Waqf Board in south Mumbai to construct his high-end residence, 'Antilla'. The letter also demanded the release of IM operative Danish.
On Tuesday, Reliance vice-president SP Nanda filed a police complaint after meeting with police commissioner Satyapal Singh.
The crime branch has launched a probe into the matter and retrieved the CCTV footage from Ambani's Maker Chambers office at Nariman Point. Police are trying to identify the suspect who delivered the letter on Sunday amid heavy security around the premises.
Police are doubtful about the legitimacy of the letter as it does not carry the official IM logo. Also, any previous instance of the group issuing any forewarning has never been recorded.
Citing sources from the Anti-terrorism squad (ATS), TOI reported that the rebel group had previously sent five mails to news channels claiming responsibility for terror attacks.
The letter also did not mention the full name of the IM operative in custody. Three people of the same name were arrested in various cases, but police believe the demand is for the release of Mohammed Danish Ansari who was arrested in January for giving shelter to the Bhatkal brothers.
