Vandals accused of smashing windows at Blackpool FC’s Bloomfield Road ground are being hunted by police.
Ball bearings were used to break four windows at the reception, and executive boxes located above the main entrance.
Police were called just after midnight on Friday after security staff discovered the damage.
A Lancashire Police spokesman said: “Damage has been reported to the police at the ground and has been logged as a crime.
“The matter is now under investigation and we will be going through the process of checking any CCTV available.
“We would ask who might have been in the area or has any information to contact police.”
The attack comes just one day before Blackpool’s final game of the season when groups of fans are expected to come together and protest against chairman Karl Oyston and how the club is run.
The protest has been named “Judgment Day” by fans after the chairman asked fans at the start of the season to “judge me at the end of the season.”
