According to reports in Deutsche Welle, staff at a German nursing home contacted the police on Friday after they noticed two men were missing from the centre.
The men were reportedly found at the festival, which takes place in the northern German town of Wacken, Schleswig Holstein, at 3am. A police spokeswoman described the men as “disorientated and dazed”.
The pair were apparently reluctant to leave the party but were escorted home by police with the help of a taxi and patrol car.
Speaking to broadcaster Norddeutscher Rundfunk, police spokeswoman Merle Neufeld said: “They obviously liked the metal festival. The care home quickly organised a return transport after police picked them up.”
