Rio de Janeiro (CNN) -- Security for Pope Francis' visit to Brazil has been raised after an incident involving his motorcade, a Brazilian federal official told CNN. The papal visit is now classified at the highest level of security -- it was raised to "high risk" from "medium risk" after his car got stuck in a crowd of enthusiastic followers Monday, the official said. The source says the problem in part stemmed from the pope instructing drivers not to avoid crowds. After Francis arrived in Brazil on Monday, he got into a silver hatchback Fiat for the drive from the airport to downtown Rio de Janeiro. Along the route, the vehicle became pinned between a bus and a crush of well-wishers who were reaching into the car to touch the pope.
