Abhinav , is there any chance that the newspaper photo may not be yours? Can't it be taken by someone sitting whereabouts you were - a few rows up,down right left etc ?. I'm sorry but it is quite possible that you were not the only one shooting at that exact moment . It is also pointless of an Indian newspaper to bother stealing an image when they probably have many photographers there in the middle of the action .
While watching sports on TV , surely some of you have noticed how many flashes burst at the same time among the crowd when the camera shows the spectators .
The exposure is quite different in the 2 photos . The newspaper photo has lost details on the dark stadium top where as yours seem perfectly exposed . The newspaper photo also looks like a high ISO shot considering the noise it overall has.
It is best to check some ratios and angles carefully to be sure the shot is yours.

EDIT : I did some and here is what I found .
You have posted your image about 11.9-12% larger than the newspaper image - I reached that figure by just by measuring the helium balloon from one end to other in each photo. This ratio should be consistent everywhere in the photo .
Then I measured the distances in the 2 photos between the top of the helium balloon and a certain point of the stadium top directly above it . And the ratio of the 2 distances is %13.7 .
I'm sorry but the newspaper PHOTO IS NOT YOURS . It has been taken by someone sitting a few rows above you . ( your angle between top of helium balloon and top of stadium is larger than his )
