"DILIP Kumar! Teri Vyajantimala ko kahan chod diya?" jibes the clerk, his large hand grabbing the eight-year-old’s thumb, pressing it savagely into the inkpad, then making a blue blob on the freshly drawn column of the ‘official document’. The wisecrack — less insensitive than ill-timed — can’t make Dilip Kumar, a ‘rescued’ zari karigar, smile. Shirt buttonless till the waist, spindly frame limp from a 50-hour, 2000-km journey over two trains, he is hungry, tired. Above all, he’s confused. Since March 4, Dilip has been asked his name — and his father’s — countless times by numerous adults in various locations, with none caring to explain to him the point of the interrogation. This latest round, by a bevy of labour officials in the GRP verandah of the Sitamarhi railway station, is equally incomprehensible. At the back of his mind a fear refuses to go away: ‘‘Am I to be sent to jail?’’ The worry is multiplied over and over again on the faces of the 49 kids sitting silently on the floor around. ‘‘Will they really release us?’’ they whisper to each other as no adult cares to explain. And they wait uncertainly, as they have been doing for the last 60 days. UNOFFICIAL estimates — the state hasn’t documented this industry’s ‘growth’ — suggest that about 8,000-10,000 children, mostly from Bihar, slave 12-16 hours every day in countless zari embroidery units in the slums of Mumbai.
