Newly-crowned IPL champions Kolkata Knight Riders were today accorded a grand felicitation by the state government at the packed Eden Gardens, but the hour-long programme turned sour when chaos followed scuffles by some frenzied fans with policemen outside the venue leading to injuries to several people.

After the 67,000-capacity stadium filled to the brim, the gates had to be closed denying entry to about 30,000 more who had to remain outside when the programme was on.
