A footpath dweller killed a coconut vendor, Mohammed Ali, 63, at Marine Lines after the two got into a heated argument on Monday when the latter objected him from littering near his stall.

The police said that the accused Rajesh Vishwakarma, 39, had brought food from a religious place nearby and was eating it near the stall. Ali then suggested to him not to litter around the stall. "This got Vishwakarma fuming who then got into a heated argument with Ali and their verbal blows snowballed into fisticuffs. In the fit of rage, Vishwakarma picked up a paver block from nearby and hit Ali on the head with it. Ali was then rushed to the nearby Bombay Hospital but the doctors declared him brought dead," said an officer attached to the Azad Maidan police station where the murder case was registered.
