Police have released images of a man they want to speak to following an assault at a retro 1980's music festival.

The attack happened at Let's Rock Scotland in Dalkeith Country Park, Midlothian, at around 11pm on Saturday, June 15.

Officers believe the man pictured may be able to assist with their enquiries.

Police constable Gavin Donaldson said: "As part of our enquiries we're eager to trace the man pictured.

"I'd ask anyone who recognises him and can help us identify and trace him to contact officers as soon as possible."

This year's Let's Rock Scotland featured the likes of Erasure's Andy Bell, Kim Wilde, Jason Donovan and Big Country.
