Police are urging Montrose and Arbroath fans attending Saturday’s clash at Gayfield Park to behave responsibly.
The plea came after concerns that the behaviour of a minority of fans at recent matches and in the wider community has fallen below the level expected.
Chief Inspector David McIntosh, Local Area Commander, Angus said: “Derby football matches should be about the football clubs, community and a family day out.
“It is disappointing that a minority of supporters have detracted from this at previous fixtures.
“There is a considerable policing plan in place and we will work with the clubs to ensure there is no repeat of the disorder.
“We would ask that supporters arrive early, act responsibly and enjoy the occasion.
“To those that are contemplating being involved in disorder at the match or in the community away from the ground there will be consequences to your actions.”
John Christison, Chairman of Arbroath Football Club said: “Arbroath Football Club look forward to welcoming Montrose FC to Gayfield and hope that the last derby clash of the season will be enjoyed by a healthy support from both clubs and played in a great sporting spirit.
“However the safety of all spectators is paramount and I would like to remind all supporters of both teams to be on their best behaviour and not to bring any type of pyrotechnic devices to the game.
“These items are extremely dangerous and Arbroath FC will take decisive action if any supporter is found in possession of such a device at the match.
“The club also take a very strong stance on anti-social behaviour and will fully support and cooperate with Police Scotland to maintain the safety and enjoyment of all supporters.
“Due to an anticipated larger than normal crowd please arrive early, act responsibly and proudly support your team.”
The Board of Directors at Montrose Football Club said: “Following after match disturbances at the previous Arbroath v Montrose match, in addition to setting off smoke bombs, Montrose FC wish to re-emphasise to supporters, anyone involved in similar incidents will be banned from attending future matches.”
