The nearly 1,000 policemen who entered the large park in the heart of Mathura were completely ambushed. From treetops, bullets showered down on them. On the ground, squatters- a heaving, ferocious mob of 3,000 - used swords, sticks and grenades. Flames raged as they set gas cylinders on fire. It took at least two hours before the squatters deserted Jawaharbagh, which they had moved into two years ago.
