Watch the moment Sam Fender warns fans that they're 'out' if they are fighting during his concert. 

The Geordie singer-songwriter wowed Glasgow fans at his OVO Hydro gig last night. 

But one small part of the show was interrupted by an apparent incident in the crowd, which resulted in Sam warning the crowd about fighting.

In a video taken in the arena, the Seventeen Going Under hitmaker stops his performance of Spit of You. 

He can be heard telling someone: "If you're fighting, you're ****ing out." 

You can see the moment below.

WARNING: Video contains offensive language.

Cheers can be heard in the audience before Sam resumed his performance. 

This comes after the OVO Hydro counted tickets and revealed that Sam is the biggest selling artist for a single show at the popular venue.
