Arsenal fans write to Spanish ambassador over 'violent uniformed thugs' in Madrid police

Arsenal fans have described Spanish police as "violent uniformed thugs" in a letter sent to the country's UK ambassador, UEFA and supporters' groups in England and Europe.
The letter is from the chair of Arsenal Independent Supporters' Association (AISA) Lois Langton and it relates to the treatment visiting fans received from Spanish police after Atletico Madrid's 1-0 win in the second leg of the Europa League semi-final earlier this month.
