Police in the southern German town of Marktl-am-Inn didn't release the exact words of the graffiti but said it referred to the current sex-abuse scandal plaguing the Roman Catholic Church, The Washington Times reported.
"The wall over the entrance door of the Pope birth house had insulting contents written in blue," said a Bavarian police report, which the Times translated with the help of a computer program. "The writer obviously used a lacquer spray can to write 30 centimeter letters."
Police estimated the vandalism caused about $2,000 worth of damage. No suspects have been identified.
