Mumbai police officer Sachin Waze, arrested in the probe into recovery of explosives from a car near industrialist Mukesh Ambanis residence, was on Sunday remanded to the National Investigation Agency (NIA) custody till March 25 by a court here. The NIA, which arrested Waze (49) on Saturday night, brought him to the court in south Mumbai after taking him to a local hospital for his medical examination, an official said. The court remanded him to the central agencys custody for further probe in the matter, he said. The NIA, while seeking Wazes custody for 14 days, told the court that they had received some inputs about his role in placing gelatin sticks in the SUV that was found parked near Ambanis multi-storey residence Antilia on February 25, and that when he was questioned about it, he admitted his involvement. Following that, Waze was placed under arrest, the probe agency said. Waze has been arrested under IPC sections 286 (negligent conduct with respect to explosive substance) 465 (forgery), 473 (making or possessing counterfeit seal, etc with intent to commit forgery), 506(2) (punishment for criminal intimidation), 120 B (criminal conspiracy) and relevant provisions of the Explosive Substances Act, the official said. In its remand plea, the NIA submittedwitnesses statements to show Wazes involvement in the case. The central agency also told the court that his custodial interrogation was required to unearth the conspiracy and gather evidence. Talking to PTI, Wazes advocate Sudeep Pasbola, however, said the arrest has been made only on the basis of suspicion and that there was no concrete evidence against him. The court remanded Waze till March 25, but kept the matter for further hearing on Monday. The court has asked the NIA to show what evidence it has collected and what is the stage of investigation, Pasbola said. Another defence lawyer, Sunny Punamia, submitted before the court that Wazes arrest was completely illegal. The argument placed before the court was that the accused has been arrested solely based on suspicion and no prima facie case is established in the FIR. Therefore, if no prima facie case is established on a bare reading of the FIR against the accused, the detainment and arrest of the accused itself is completely illegal and even one days incarceration of the accused would be violative of his constitutional rights, he said. The lawyer also said that Wazes arrest was also illegal as the accused was not informed of the grounds of the arrest, and he wasnt given an option to seek legal help and make a call to a relative of his choice. On these grounds, his custodial interrogation is not warranted, its arbitrary and the accused must be released on bail forthwith as the investigation has not been conducted on the settled principles of law, he added. Waze was summoned at the agencys Mumbai office at Cumballa Hill in south Mumbai around 11.30 am on Saturday to record his statement. The spokesperson said that Waze was arrested after being questioned by the NIA officials for around 12 hours. The case was handed over to the NIA after the mysterious death of Thane-based businessman Mansukh Hiran, who claimed that the vehicle had been stolen a week earlier. His body was found in a creek at Thane on March 5. Hirans wife had claimed that her husband had given the SUV to Waze in November, which the officer returned in the first week of February. However, during his questioning by the ATS, Vaze had denied using the SUV that was in possession of Hiran. Credited with eliminating 63 alleged criminals in encounters, Waze, a 1990-batch officer of the state cadre, was suspended in 2004 over his role in the custodial death of a 2002 Ghatkopar blast suspect Khwaja Yunus and was reinstated last year. Waze, who led the team that arrested journalist Arnab Goswami in November last year in a suicide abetment case, had joined Shiv Sena while he was under suspension. Chief Minister Uddhav Thackeray recently said Waze was a member of Shiv Sena till 2008.
