The Mumbai crime branch on Sunday detained a few suspects, including a property developer from Dharavi, in connection with the shooting at hotelier BR Shetty earlier this month.
Crime branch sources said they have captured some suspects, but the operation is still underway as they are looking for other remaining suspects.
The names of the suspects are likely to be made public on Monday along with the motive behind the attack. Sources said three units of the crime branch were working on the case.
On October 3, two unidentified shooters on a bike fired four rounds on Shetty at Andheri.
