[CEF]

Were there till rolls thrown onto the field of play during the match (some aimed @ Krul) - Yes
Therefore if the person arrested @ end of match is guilty of such then yes he should be charged.
When Jase was arrested did a group of 20 or 30 run towards the police/stewards - Yes
Therefore this could be deemed as hostile.
Could the club be fined for failing to control the crowd (again the throwing incident) - Quite a possibility
Therefore can i ask what you are expecting the club to come out and say publically regarding the incidents. Until all facts are looked @ there's not a great deal they can do. It all started because someone pushed it too far with throwing the till rolls which is an offence and therefore someone was arrested then it all banked rolled from there.
Over reaction from police/stewards - Yes definatley but it did all start with someone commiting an offence
