Hundreds of music fans were left frustrated after being denied entry to The Weeknd's Abu Dhabi gig, prompting organisers to issue a statement explaining why.
FLASH Entertainment, the promoters behind the Yasalam post-race concerts, said a number of fans arrived at once and a decision was made to close the gates on safety grounds.
And concert bosses condemned reports of fans storming the gates to gain entry to the du Arena gig.
A statement issued by the organisers said: "Health and safety is our number one concern.
"Du Arena can easily accommodate 35,000 people.
"A large number of fans arrived simultaneously to The Weeknd concert and gates were closed for safety.
"We understand this is disappointing and frustrating.
"It is disappointing to hear there were instances of inappopriate fan behaviour.
"The necessary teams are working to ensure a smooth and safe entry ahead of the following concert."
Despite the crowd trouble, thousands of Abu Dhabi music fans enjoyed The Weeknd's gig, the second in the post-race concert series this weekend.
Tonight sees Sam Smith take to the stage at du Forum, while Guns N' Roses do the honours of rounding off an epic weekend on Sunday.
