The Samta Nagar Police in Mumbai have invoked the stringent Maharashtra Control of Organised Crime Act (MCOCA) against alleged gangster Yamesh Dilip Darekar, alias Dada, and members of his alleged syndicate in connection with an extortion and assault case in Kandivali East, officials said on Friday.

The action follows a violent incident in Poisar on June 15, when a local resident was allegedly assaulted after refusing to pay extortion money.
