ABERDEEN have sent a warning to a "minority" of their fans over unacceptable behaviour in recent matches.

The Pittodrie outfit have issued a statement to remind fans over their conduct in the stands.

It comes after 14 pyrotechnics were set off in last Saturday's match against St Mirren.

The Dons revealed that due to the damage caused by the pyro, they will need to fork out at least £1,000 for repair works. 

A statement reads: “It has been great to see fans back at Pittodrie enjoying our victories over Dumbarton, Raith Rovers and St Mirren.

“The backing from the majority of fans has been superb, however we need help from our supporters when it comes to stopping the use of pyro and other unacceptable behaviour at matches.

“The club wants to make fans aware of the challenges faced at the St Mirren fixture last weekend and the impact this has had on Aberdeen.

“At least 14 pyros were discharged at the game – some of these damaged the pitch and burnt surrounding Astro turf which will be costly to repair. 

“More than 40 seats and frames were vandalised in the Red Shed at a cost of at least £1k to the club.

“In addition to this an object thrown at one of the away supporters’ buses caused significant damage and is being treated as a criminal act. More information can be found in the police statement below.

“For the past 10 years, St Mirren games have not required a police presence. 

“As a result of these issues, that is now under review and could change. With that comes yet further unnecessary cost for the club.

“We strongly advise that no balaclavas are worn whilst approaching or within the stadium – this will only attract attention, it unnerves other fans and it’s not an image we want to encourage.

“A small, disruptive group is tarnishing the reputation of the club, impacting the matchday experience for others and costing us a lot of money that could be better spent elsewhere.

“We would urge our supporters who don’t cause these issues to help us deal with this and report any unacceptable behaviour before it escalates and our Red Shed licence is taken away by the authorities.”
