Football fans have vandalised trams in Sheffield after a match between Sheffield Wednesday and Millwall at the weekend.
The match finished 3-2 in the home side's favour, with Wednesday scoring a late winner to continue their good start to the season.
Things turned sour after the match, however, as fans - thought to be from the away side - damaged the city's trams.
A spokeswoman for Stagecoach Supertram said there was a 'significant amount of damage', including broken doors and smashed windows, although no-one was injured.
Stagecoach Supertram have provided CCTV footage to the police to help with their investigation.
