Two Dutch brothers among a group who attacked a waiter at a cafe in Prague have been jailed for six and five years for public order offences and serious assault.

The waiter was reportedly attacked when he asked a stag party group to leave a pavement terrace where they were drinking their own beer.

Seven people were arrested, three of whom were given suspended sentences and banned from returning to the Czech Republic for five years. Two others were acquitted after it became clear from video footage that they had tried to break up the group.

Arash and Armin N. have been held in custody since the incident a year ago, which left the victim in hospital for three weeks.

Under the terms of a treaty with the Czech Republic, the two men will be allowed to return to the Netherlands to serve out their jail time, but only once any appeals have been heard, broadcaster NOS said.

The public prosecution department, which had called for sentences of 10 to 18 years, has said it will appeal.

The brothers have also been ordered to pay their victim €75,000.
