This was my experience of it too. I was at the front of the North Stand and was unable to exit the ground so just had to stand there and hope for the best. They were pelting us with coins and trying to goad us onto the field, some were trying to get into the stand. The police and stewards were heavily outnumbered and just stood and watched. They then came charging down the stairways and caused absolute mayhem as fans couldn't get out.
