In March 2002, the Seaburn Casuals (a Sunderland A.F.C. firm) fought with hooligans from the Newcastle Gremlins in a pre-arranged clash near the North Shields Ferry terminal, in what was described as "some of the worst football related fighting ever witnessed in the United Kingdom".[27] The leaders of the Gremlins and Casuals were both jailed for four years for conspiracy, with 28 others jailed for various terms, based on evidence gained after police examined the messages sent by mobile phone between the gang members on the day.[28]
