There were other guests who alerted the guard that a minor person had infected. The guard confronted the boy, who showed a digital ID card and admitted it was false.
It turned out that the action had been developed with the help of a software where a photo was entered, a false name and date of birth.
The boy tells in interrogation that his friend created the fake ID document for fun. He says he did not think he did anything criminal because he was not asked to show the identification at the entrance.
