The crime branch on Thursday claimed to have solved the mystery of the murder of a moneylender in the Dhobi Talao area last month with the arrest of four of the alleged killers.
On March 30, the assailants entered the office of Alpesh Jain, a licensed money lender, at his office in Dhobi Talao and attacked him.
After killing him, they fled with cash and jewellery.
Joint Commissioner of Police Himanshu Roy said Rs 2.5 lakh and 300 gms of gold jewellery worth Rs 5 lakh have been recovered from the assailants.
The FIR said assailants stole Rs 8 lakh.
Roy said the police are on the lookout for more assailants who may have also been involved in the crime.
The arrested killers were identified as Mohammad Ilyas Ahmad Sheikh, Atul Shetty, Abdul Rehan Abdul Aziz Sheikh and Mohammad Azim Abdul Salim Sheikh.
Roy said all of them are hardened criminals with cases ranging from dacoity, murder to attempted murder having been registered against them.
“They are from Vasai-Manikpur area and had ganged up for this crime,” Roy added.
Roy said the killers had kept a watch on Jain’s movements and were aware that he would be alone in the office.
He added that the case was solved because of “electronic and human intelligence” mounted by the Unit III crime branch that was conducting a parallel investigation with the Azad Maidan police station where the case was registered.
