According to the sources, the DNA of a 35-year-old Greek football supporter has been found on one of the knives police collected from the scene of the deadly attack, that also had traces of the victim's blood on it.

The 35-year-old, in testimony given the previous Friday, claimed that he had a knife on him when the clashes started that he then lost. The 35-year-old was arrested and is already in Nafplion prison serving an earlier outstanding prison sentence of 12 months and a fine for his involvement in previous incidents of football fan violence in the town of Volos.
