(CNN) -- Two private security company workers were shot at with an air gun near where Pope Benedict was to hold Mass in Germany on Saturday, police said.
Four shots were fired, but no one was injured, Dirk Sauter, a spokesman for Erfurt police said in a statement.
One person has been taken into custody.
"The incident happened at a security check at the outer perimeter of the security zone" for the pope's Mass, Sauter said.
A spokesman for the German Interior Ministry said the incident took place "several hundred meters away from the actual venue, and certainly no one fired shots at the pope."
