The Pontiff was greeting adoring fans when one over-enthusiastic member of the crowd pulled his robe, forcing him to topple forward onto a disabled man in front of him.

With the help of his alert bodyguards, he righted himself before raising his voice to the excited crowd.

"No seas egoísta. Qué te pasó, no seas egoísta", the Daily Mail reported him as saying, which translates to "don't be selfish, don't be selfish".

His gestured his annoyance using his arms for emphasis.
