Accrington Stanley have had a number of break-ins over the last few weeks which have been reported to the police.
Damage has been done to the pitch and to areas around the Wham Stadium and items have been taken.
"It is so frustrating as we have worked hard on the pitch and around the ground over the last few years and it's the actions of a few which are making life difficult for us," said Managing Director David Burgess.
"We are a community club and these people are spoiling it for everyone.
"The supporters are superb on match-days. They self-police the Fanzone and other areas of the ground which are pristine.
"We have security cameras installed and the police have been given the footage of the break-ins and we will be increasing our security.
"Items, such as leaf blowers and food, have been stolen and this hinders the every day running of the club."
