St Mirren have fired a warning to fans after a member of the public entered the Simple Digital Arena and ran on the pitch on Sunday afternoon.
The Premiership strugglers have passed their CCTV footage onto police as they investigate how it happened and warned supporters of the dangers of trying to get into the ground.
St Mirren have a fence around the stadium which has anti-climb spikes as well as being high enough to cause serious injury if someone fell from it.
And they urged the public to remain at home while lockdown is in place during the coronavirus crisis and reminded fans of the government guidelines.
