Rediff.com brings you a selection of images of fans taking to the field of play to make a point or gain attention.
Pitch invasion is very much part of sports history. True, there's nothing nice about it, but, certainly, much to shout about.
With the football season in full swing all over the world, the pitch invaders are back and how!
A fan running, or streaking, on the field and interrupting play is certainly condemnable. But, for the spectator, it's pure fun; there's nothing negative about it.
Instead, it's an enjoyable moment for the crowd, which always cheers wildly.
