Leicester City fans have been involved in further clashes with Spanish police ahead of their Champions League tie against Atletico Madrid.
Objects have been thrown at police and fans injured, along with unconfirmed reports of flares being set off.
BBC journalist Phil Mackie confirmed police used baton charges to clear parts of a city square.
Earlier, Spanish police said eight Leicester fans were arrested for "causing a mess" on Tuesday night.
Social media videos from Plaza Mayor, where Leicester fans had been told they could gather, show a group of police being targeted with missiles and fans chanting "Gibraltar is ours".
