The trio include a sub-inspector attached to the flying squad of the department, Balasaheb Patil and a peon identified as Madhukar Rathod, besides a private person.
ACB DYSP (Thane unit) Mamta D'souza said the accused had allegedly demanded bribe from a tour & travel operator whose vehicle had been seized in connection with some offence.
Initially, a demand of Rs 1 lakh was made by Patil but the amount was subsequently brought down to Rs 40,000 and the complainant paid the first instalment of Rs 15,000 to Rathod.
A case under various sections of the Prevention of Corruption Act 1988 was registered against the trio. However, no arrests are made yet.
