Pope Francis rebuked well-wishers in Mexico for being selfish, after they grabbed him and caused him to fall onto a child in a wheelchair.

Francis, who is currently in the middle of a six-day visit to Mexico, was in the city of Morelia on Tuesday greeting the crowds after an open-air stadium mass specifically for young people, when one well-wisher grabbed his arm.

He would not let go of the Pope, causing Francis to lose his balance and fall onto a child in a wheelchair.

The Pope recovered, kissing the child on the head.

But he then shared his frustration, shouting to the person who had grabbed him in Spanish: "No seas egoísta. Qué te pasó, no seas egoísta", which translates to mean "Don't be selfish, don't be selfish."

Pope Francis has endeavoured to engage with the public in a face-to-face manner, choosing to travel in open topped cars, rather than the bullet proof pope-mobiles that were introduced after the attempted assassination of Pope John Paul II in 1981.
