A convict in the 1993 Mumbai serial bomb blasts case was fatally attacked by five inmates in Kalamba Central Jail in Kolhapur on Sunday, police said.

Prima facie, an argument with other inmates over taking a bath in the bathroom area of the jail resulted in the attack on 59-year-old Munna alias Mohammad Ali Khan alias Manoj Kumar Bhawarlal Gupta.

Mohammad Khan was serving life imprisonment in the serial blasts case.
