I read about this in an AP newswire and rewrote it in my own words to avoid copyright problems:

It seems that a diehard fan of the soccer club Real Betis died last year. But he asked his son to take his remains to every game.

So sonny boy did one better: he renewed his membership, entitling the ashes to a seat at the games…

Well, this is not the end to it: the management of the field asked him not to bring his fathers ashes anymore, because they were in a glass urn, which they considered a dangerous object :-O

So the son went back next match with the ashes in a cardboard box. Incredible but true…
