Mumbai: Maharashtra Home Minister Anil Deshmukh said that the Senior IPS officer Hemant Nagrale was appointed as the Mumbai city commissioner on Wednesday in place of Param Bir Singh. Param Bir singh was transferred to home guards, on the allegations linked to the Mukesh Ambani security scare.

In this case a police officer Sachin Waze arrested by NIA recently. The investigation has become a huge embarrassment for the Maharashtra government, with the opposition BJP accusing Chief Minister Uddhav Thackeray of shielding Sachin Waze, a controversial cop who was once a member of his Shiv Sena.

The case involves a Scorpio SUV carrying gelatin sticks found abandoned on Mumbai’s Carmichael Road, near Mukesh Ambani’s 27-storey home Antilia, on February 25. It carried a threat letter to Mukesh and Nita Ambani. Sachin Waze was the first investigating officer in the case but the NIA suspects he played a more sinister role.

The NIA, which took over the investigation from the Mumbai police, alleges that the number plate of the abandoned vehicle was found in a car that Sachin Waze was using. On Wednesday, the top investigating agency said a person seen in security footage lurking near the Ambani home the same night was Waze, after recovering some clothes from the Mercedes car he was using.

The NIA also claims the fingerprints on the Scorpio match Waze’s and that he was travelling in an Innova tailing the Scorpio car.
