The Borivali Police booked three persons and arrested one for allegedly demanding Rs 50,000 from the supervisor of an under-construction building site in Chikuwadi, Borivali West, threatening to halt the work.

The accused took away the keys to the cement mixer, stopping the construction. This caused the cement inside the mixer to harden, rendering it unusable and resulting in a loss of approximately Rs 80,000 for the contractor.
