Maharashtra Anti-Corruption Bureau (ACB) has summoned suspended IPS officer Param Bir Singh for a third time to record his statement in connection with an "open enquiry" initiated against him on a complaint by police inspector Anup Dange, a senior official said.

The former Mumbai police commissioner has been asked to appear before the anti-graft agency of the state police on February 2, the official said. Singh, suspended by the home department last month after multiple extortion cases were registered against him, was earlier summoned on January 10 and January 18 and on both occasions he failed to appear before the ACB, he said.
