The crime branch of Mumbai police on Saturday filed a chargesheet against former city police commissioner Param Bir Singh and three others in an extortion case registered in suburban Goregaon.
This is a first chargesheet against Singh, who is facing multiple cases of extortion.
Two days back, the Maharashtra government had suspended Singh in connection with the charges of extortion.
Besides Param Bir Singh, dismissed police officer Sachin Waze, Sumit Singh and Alpesh Patel have been named as accused in the chargesheet.
The chargesheet was filed before chief metropolitan magistrate S B Bhajipale.
The complaint had been lodged by Bimal Agarwal, who alleged the accused extorted Rs 9 lakh from him for not conducting a raid on two bars and restaurants, which he ran in partnership, and also forced him to buy two smartphones worth around Rs 2.92 lakh for them.
