Prior was run out for four on the final day and when he returned to the dressing-room his bat fell against the window, shattering the glass.

The spectator in the members' enclosure directly below the window suffered a small cut on her ankle.

Prior, accompanied by captain Andrew Strauss, later apologised in person.

Strauss, speaking after the match was drawn - leaving England 1-0 up with one match to play in the series - commented: "It was one of those unfortunate incidents. It was purely accidental. Matt didn't mean to break the window at all.

"He holds all his bats against the wall and he put it there and it bounced off the other bat and hit the window. It was important that he apologised to the people below because it could have been dangerous. Hopefuly it won't happen again.

"We are always annoyed when we get out, especially run out, but that wasn't why the window got broken."
