On Instagram, the venue said: "Jesus, Mary, Joseph and the wee donkey...it's Martin Compston in Maggie's.

"He popped in after yesterday's game and spent some time with our in-house band and Maggie's very own Hugh...have we FINALLY cracked the H mystery?"

The caption refers to the final, high-ranking corrupt police officer in the series Line of Duty, as fans guess their identity after season 6.

The actor plays Detective Sergeant Steve Arnott in the show.
