IT all happened in Central Calcutta in broad daylight. Four or fivehawkers on Dharamtala Street pounced on a customer, punching and kicking him.Their ashen-faced victim, a middle-aged person, shouted for help and attracted a crowd,which freed him. Between anguished gasps for air, the man, his shirt torn, explained whathad happened. By the time he began the story, his attackers had vanished.
