Bollywood star SANJAY DUTT's medical worries have been dismissed by a prison doctor, who blames his condition on a "change in environment". Dutt was jailed for six years last Tuesday (31Jul07) for illegal possession of arms in relation to the serial bombings in Mumbai in 1993, which claimed 257 lives. But concern for his welfare behind bars was raised on Saturday (04Aug07) after the actor complained of a sense of "uneasiness". However, following a medical check-up, a source told local new agency Press Trust of India, "There is nothing serious about his condition and there was no cause for worry."
