Unknown perpetrators tried to set fire to the Romanesque church of Santissimi Pietro e Paolo in Bollengo. Mayor Luigi Ricca noted that the police "found traces of flammable liquid in the churchyard. The same group then broke one of the road signs indicating the route of the Via Francigena in the area". Since the modus operandi is similar to the case of church vandalism at the San Silvestro church in Chiaverano from June 2021, the police are suspecting the same group to be responsible. However, Mayor Ricca does not think that it is the same group. Investigations are ongoing.
