Hamburg's Bundesliga 2 match against Hannover was temporarily suspended at half-time amid crowd trouble among away fans at the Volksparkstadion.
Hannover fans had appeared to chain locks to the goalposts inside the ground in protest to the club's owners.
Fans in the away end had also held up banners that depicted Hannover chairman chairman Martin Kind between a crosshair.
Members of the stadium staff were seen on the pitch cutting the locks with an angle grinder before the match resumed, with Sebastian Ernst scoring in the eighth minute of injury time to seal a dramatic 4-3 victory for Hannover.
Amid the crowd trouble, Hannover goalkeeper Ron-Robert Zieler was also seen on the live coverage of the match stepping over the advertising hordings and approaching the away fans.
The captain was seen walking up to the supporters in an attempt to quel the crowd trouble.
Their protests were in relation to the Hannover's decision to vote in favour of the Gereman Football League's proposals to bring in a new strategic investment partners with firms CVC Capital Partners and Blackstone Group.
But the move has been met with much animosity among fans, who believe the move could come as a detriment to their clubs.
