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.

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.

Northumbria Police have asked the public for help identifying the perpetrators of today's derby match violence in Newcastle.
The force also praised its officers for their "professionalism and bravery":
