Mumbai police on Wednesday arrested three persons from Surat in Gujarat for allegedly trying to extort Rs 50 lakh from a businessman here and threatening him by citing their links with gangster Chhota Shakeel, an official said.

The complainant in the case said he had given Rs 13 crore to one of the accused, but instead of repaying the money to him, the latter along with his two accomplices threatened him and tried to extort money, the police said.
