Newcastle United management have promised to impose lifetime bans on fans found guilty of "disturbances and disorder" in the aftermath of the club's defeat to local rivals Sunderland yesterday.
A club statement said:
We were embarrassed and appalled by the behaviour of a minority of so-called fans who last night were involved in disturbances and disorder in Newcastle city centre after the match.
Newcastle United have been working with Northumbria Police, and will continue to do so, in order to identify all of the individuals concerned.
– Newcastle United
The Club will take the strongest possible action against those involved in the disturbances and will impose immediate lifetime bans on all those found guilty.
These deplorable individuals have no place at Newcastle United and bring shame on the Club and the vast majority of its proper, law-abiding, fans.
