Video: Riot police called in as Southampton and Vitesse Arnhem fans clash
Trouble flared up before Southampton's Europa League clash against Vitesse Arnhem, with police storming in after glasses, chairs and punches were thrown.
There was a peaceful, convivial atmosphere in Arnhem for the majority of the day, only for things to go awry two hours before the second leg of the third qualifying round tie got under way.
The issues arose in Korenmarkt, the city's bar district, where English and Dutch supporters had spent much of the previous 24 hours drinking together peacefully.
However, riot police and horses were called in after clashes began, which some onlookers said came after provocation from Feyenoord supporters.
Press Association Sport was told in the aftermath that a group of fans charged into the square, where a number of Southampton fans were seen throwing chairs and fighting.
Saints boast a 3-0 advantage heading into Thursday night's return leg at the GelreDome.
