PALGHAR, Sept. 12 -- The Palghar police on Friday apprehended Rohit Gavit, former Shiv Sena deputy taluka chief and son of MLA Rajendra Gavit, in connection with the assault on doctors and medical staff at a private hospital in Palghar on September 5. Gavit, who was suspended by the Shiv Sena following allegations of his involvement in the incident, was detained from Mira Road in the afternoon and taken to Boisar for questioning. Another accused Shiv Sena functionary, Sairaj Patil, was also detained from outside Palghar district in the late afternoon and brought to the district headquarters for questioning. The duo is likely to be placed under arrest on Saturday, once their interrogation and preliminary probe is completed, police officials familiar with the matter told HT. Despite the arrests, the Bombay High Court on Friday severely reprimanded the Palghar police and called the investigation "most lackadaisical" and an "eyewash". "It appears you (State) are just dodging our questions. Nothing is done. What is this investigation," the division bench of justices AS Gadkari and Kamal Khata said. The court was hearing a suo motu regarding a similar assault on doctors at a civic hospital in Dombivli in July. On September 9, it was informed about the September 5 incident at Relief Hospital in Palghar, when some Shiv Sena functionaries allegedly assaulted medical staff following a dispute over treatment and discharge of Govindas injured during Dahi Handi celebrations. The Palghar police subsequently booked 17 people, including the Shiv Sena Palghar district chief Kundan Sankhe, city chief Rahul Gharat, and deputy taluka chief Rohit Gavit. While the Sena suspended the trio and four other accused functionaries, Gharat surrendered before the police on September 7. On Friday, MLA Rajendra Gavit claimed that his son too had surrendered before police. Appearing before the division bench, chief public prosecutor Shishir Hirey claimed that Rohit Gavit had been arrested and the prosecution's major focus now was on arresting the main accused. The court however, questioned the Palghar police about why a vital piece of evidence - a bottle of saline allegedly removed from a patient - had not been seized and why the police had failed to trace even those accused who were local residents. "They're locals, right? They're not from foreign countries that you can't find them," the court said. It emphasised that the police were "failing everyday, day in and day out", and said lack of crucial details in the panchnama reflected the poor quality of the probe. Senior counsel Ashok Mundargi, appointed amicus curiae in the matter, suggested that the court monitor the probe "or the investigation will never be completed". He said that the investigation needed to be more focused. The court directed the Special Inspector General, Konkan division, to review the investigation and submit a report by September 17....
