Carlisle hosts Big Weekend featuring Lady Gaga
Thousands of music fans have descended on Carlisle for one of the biggest music events in the UK.
The city's airfield is hosting BBC Radio One's Big Weekend, with Lady Gaga topping the bill later. The Foo Fighters headlined on Saturday.
About 40,000 people turned up, and police hailed the first day as a success, with only one arrest on the site, on suspicion of assault.
It is hoped the event will generate up to £4m for the city's economy.
Almost 500,000 people applied for the 40,000 free tickets available, and selection was by ballot.
The Black-Eyed Peas, Bruno Mars, Plan B and Tinie Tempah are also taking part.
For the weekend, the airport was transformed into a small village of stages, food vans, portable toilets and VIP lounges.
Ch Insp Mark Pannone said: "The first day went very smoothly with very few problems.
"There were a few traffic hold-ups in and around Carlisle during the morning as some of the 20,000-strong crowd arrived to see some of their favourite international bands and artists.
"We expected some delays and I'm pleased to say that the motorists were very patient as we helped ease congestion.
He added: "We are looking forward to another successful day and hope that the positive atmosphere continues."
