The Central Finland Court of Appeal has ruled against releasing a Swedish national who was arrested at the start of the month at a violent neo-Nazi rally in Jyväskylä.
Three people were attacked a week ago last Saturday after fighting broke out in the town centre following a protest organised by the extreme-right group the Finnish Resistance Movement.
The man is accused of assault and of having taken part in the unrest. He was remanded in custody alongside seven other people earlier this week.
