In a big setback to ex-Mumbai API Sachin Vaze, a special NIA court on Friday sent him to judicial custody i.e Taloja jail till April 23 in connection to the Antilia bomb scare case. The court has also allowed CBI to access diaries belonging to Sachin Vaze and suspended constable Vinayak Shinde that were recovered by the NIA earlier. Vaze, who was arrested by NIA in the Antilia bomb scare is also being investigated for Mansukh Hiren's death by the NIA. The CBI, on the other hand, is investigating the 'extortion' allegations of ex-Mumbai CP Param Bir Singh against ex-Home Minister Anil Deshmukh and Sachin Vaze. CBI records statements from Sachin Vaze, Param Bir Singh As per sources, Param Bir Singh reiterated his 'extortion' charge against former Home Minister Anil Deshmukh while he recorded his statement with the CBI on Thursday and submitted the messages he received from ACP Patil. Sources added that Param Bir Singh also submitted a few documents and the details of key meetings. Meanwhile, former encounter specialist Pradeep Sharma was also summoned by the NIA on Thursday after suspended API Sachin Vaze allegedly named him in his confession. The former cop & Shiv Sena leader was questioned for over seven-and-a-half fours on Wednesday following which he was once again summoned on Thursday. The Supreme Court has upheld the Bombay HC's order of allowing a 15-day CBI preliminary enquiry of Singh's 'charges'. Antilia bomb scare & Mansukh Hiren death case On February 25, at around 3 PM, a car (green Scorpio) laden with explosive gelatin sticks along with a threatening letter was found by Mumbai Police, outside the Ambani residence - Antilia. A primary investigation from the CCTV revealed that the car had been parked near the residence since 1 AM, intervening night on between Wednesday-Thursday. Later on March 5, Mansukh Hiren, the owner of the car in question, was found dead at the Kalwa creek - with police claiming that he committed suicide by jumping into the stream. With the deceased wife alleging murder, Maharashtra ATS probed and arrested a bookie and convicted cop Vinayak Shinde in connection with Hiren's murder. Later, then-Mumbai API Sachin Vaze was arrested by NIA on March 20 for his alleged involvement in placing explosives in the aforementioned car, invoking UAPA against Vaze. While Vaze has been suspended again from police service, his superior - Mumbai CP Param Bir Singh has been transferred to Home Guards due to 'lapses' in the probe. He has sent an 8-page letter to CM Thackeray, HM Anil Deshmukh and Gov Koshyari alleging that Deshmukh had demanded Vaze to collect Rs 100 crores from 1750 pubs in Mumbai per month - Deshmukh has resigned from his post after a CBI enquiry has been ordered against him by Bombay HC.
