A Spanish football supporter was found dead on Monday in Madrid where 52 others were arrested after a night of revelry to celebrate their team's victory over Germany in the final of Euro 2008, police said.
A municipal street cleaner found the 40-year-old man, wearing a red shirt of the Spanish team, at dawn in a pool of blood in the centre of the capital.
There was no indication of foul play, and police said he probably bashed his head on the ground when he fell over drunk.
Police also announced that 52 supporters were arrested in Madrid during the night of wild celebrations at Spain's first major international football trophy in 44 years.
They were detained for acts of vandalism and public disorder around the Plaza Colon, where 65,000 fans watched the match beamed live from Vienna on giant television screens.
