Sachin Waze, an accused in the Antilia bomb scare-Mansukh Hiran murder case, is currently admitted to a hospital in Thane.
The NIA in its charge-sheet also said Sachin Waze placed the SUV near Mukesh Ambani's house in Mumbai to regain his reputation as a 'super cop'.
Sachin Waze, who was assistant police inspector with the Mumbai crime branch before his arrest, joined hands with others to place the SUV and a threat letter near Ambani's residence, it said.
The agency filed the charge sheet two days before the end of the 30-day extension granted to it by the court last month to complete the process, a defence lawyer said.
The central probe agency said this while seeking a 30-day extension to file a charge sheet in the Antilia bomb scare-Mansukh Hiran murder case.
