Here is an article dated 11/1/10 sent to me from Gespenstliebhaber13 in Austria translated to English.
Danger strikes the village of Retz’s Halloween-Umzug “Halloween Parade”. Mass abductions reported by mysterious individuals dressed in elaborate costumes, causing a panicked crowd to abruptly end the parade. Police found a victim’s camera with an image of one of the possible abductors. No clear answer has been found for the reason or who perpetrated the attack.
