Iqbal Kaskar, brother of underworld don Dawood Ibrahim, and his two associates have been booked on charges of extortion and assault following a complaint by an estate agent, police said on Tuesday.
An FIR was registered last night at Byculla police station after a complaint by Salim Shaikh, an estate agent that Kaskar and his men had demanded Rs three lakh after thrashing him last Friday, police said.
The alleged incident occurred in a room at Damarwala building at Pakmodia Street in South Mumbai's Bhendi Bazar area, police added.
The case was subsequently transferred to J J Marg police station as the place where the alleged extortion took place falls in its jurisdiction.
"Kaskar and two others were booked under IPC sections 385 (Putting person in fear of injury in order to commit extortion), 323 (Punishment for voluntarily causing hurt) and 34 (Acts done by several persons in furtherance of common intention)," said Anil Madvi, senior inspector at J J Marg police station.
The 48-year-old victim, who is a resident of Byculla, first approached the local police station where the FIR was registered and then the matter was transferred to J J Marg police.
Kaskar had been deported to India from the United Arab Emirates in 2003. Dawood's fifth sibling was wanted in a murder case and his alleged role in the controversial Sara Sahara case where a building came up illegally on government land but a court acquitted him in both the cases in 2007.
