Physical altercations have broken out in the stands at St Jakob-Park ahead of this evening's Europa League final between Liverpool and Sevilla.
Video footage appeared to show supporters of both sides throwing punches before stewards and the police moved in to break it up.
A particular shot showed one fan with a bleeding head after he had allegedly been struck by a bottle.
The problems have seemingly since subsided, with order having been restored.
