The terrorists who waged war on Mumbai for three days were fuelled by drugs including cocaine, it has been reported.
Indian officials believe terrorists injected themselves with cocaine and LSD before carrying out the 60 hour attack that killed nearly 200 people.
They also reportedly carried drugs and syringes in their bags alongside their weapons and ammunition, with one terrorist injecting himself with stimulants to enable him to continue fighting despite suffering a life-threatening injury.
The extremists had previously used steroids to bulk up their bodies while training in Pakistan for last week's deadly assault.
"We found injections containing traces of cocaine and LSD left behind by the terrorists and later found drugs in their blood," UK newspaper Telegraph reported an Indian official as saying.
"There was also evidence of steroids, which isn't uncommon in terrorists.
"These men were all toned, suggesting they had been doing some heavy training for the attacks. This explains why they managed to battle the commandos for over 50 hours with no food or sleep."
Indian officials believe the training was organised by the Lashkar-e-Taibat terrorist group and conducted by a former member of the Pakistani army.
"They underwent training in several phases, which included training in handling weapons, bomb making, survival strategies, survival in a marine environment and even dietary habits," an officer was reported as saying.
Indian newspapers have published a dramatic picture of the Azam Amir Kasav, the only surviving terrorist.
Appearing dazed and lying on his back with his eyes open, the 21-year-old is surrounded by life support machinery.
An Indian TV station previously released footage reportedly showing Kasav being beaten first by police and then an angry mob after he stumbles out of a car.
With fellow train-station terrorist Abu Ismail shot dead inside white Skoda, which was brought to a stop by a volley of bullets at a road block, Kasav appears to play dead as he is beaten with police batons before the crowd joins in.
A senior police officer then steps in to stop the assault as Kasav remains curled into a ball.
The official death toll remains at 172, including two Australians, with 239 people wounded.
