In his report forwarded to the Municipal Commissioner Arun Bhatia on Friday evening, divisional sanitary inspector Waman Raghunath Tade has accused sub-inspector R C Pisal of Deccan Gymkhana police station and four others of threatening him with dire consequences in case he failed to withdraw the complaint against Joshi hospital.

Assistant Commissioner of Police Dnyaneshwar Chavan admitted that sub-inspector Pisal had indulged in a heated argument with Tade when he had gone to his house to record a supplementary statement on Friday night. However, he denied the allegation that Pisal threatened Tade and pressured him to withdraw the complaint.

Pisal was not available for comment. Inspector Ram Kondhalkar said Pisal had proceeded on a leave since this morning to attend the wedding of his relative.

Hospital employee Sayyanna Dhangar, from whom seven bags of hospital waste was recovered, was arrested late last night. He was produced before Judicial Magistrate (First Class) V N Satpute who granted him a bail in the afternoon.

On receipt of the report, Bhatia reportedly asked Tade to lodge a formal police complaint against Pisal and the others. However, no such complaint was filed at Deccan Gymkhana police station till late night.

In his report to the Municipal Commissioner, Tade has alleged that sub- inspector Pisal, head constable Shashikant Sakharam Dhadi and three others approached him at his residence in Yogi Society, Dhankawadi around 11.45 p.m. on Friday.

``The policemen told me rudely that Assistant Commissioner of Police Dnyaneshwar Chavan had summoned me. Later, they insisted that I should withdraw the complaint. They also threatened to implicate me in some cases if I failed to do so,'' Tade alleged in his report to Bhatia.

He claimed to have told the policemen that he had filed the complaint as a PMC officer and that he could not withdraw it without directives by the Municipal Commissioner.

Tade alleged in his FIR that the policemen insisted that he should go with them to meet the ACP. ``When I demanded to know why they were bothering only me when there were so many others who exposed the racket, they curtly said it was so because I had lodged the formal complaint,'' he charged. ACP Chavan said the decision of recording Tade's statement was taken after discrepancies were noticed in his complaint.
