Fourteen people were injured at an Oklahoma casino when a storm knocked over trusses at the entrance at a Backstreet Boys concert. The Backstreet Boys were all set to perform at The Colosseum within the WinStar World Casino and Resort.

The weather conditions got worse and so officials started to vacate everyone from the outdoor area at around 5 pm after seeing a lightning not more than  4 miles away from the concert, according to Kym Koch Thompson, spokesperson for the organisation, as reported by E!News.

Even though many people were asked to move and stay under shelter, the people standing in lines did not heed the warning given.

"The storm hit and knocked over the concert entrance trusses with 70 [to] 80 mile an hour winds and heavy rain". According to reports, the incident happened at 5:30 pm. The 14 injured people were treated at the scene and then taken to a local hospital for further procedures," Thompson said.

"We know that fans often suffer through inclement weather for their favourite acts, but this was an unusual event and our thoughts are with those who were injured during this storm," he added.

Kevin Richardson tweeted about the situation and said they are waiting to get an update on the damages caused.

"Hey folks! Severe weather, high winds and rain just passed thru here in Thackerville, OK. Emergency crews are on the scene as tent collapsed and some folks who were seeking shelter were injured. Waiting to determine damage to our stage and production."

Later, he said the show will be cancelled for the night due to the storm which caused a lot of damage.

"Update... unfortunately, due to damage sustained in the storm earlier this evening, we are unable to perform the show tonight," he wrote. "Safety is always #1. Keep your tickets because, Backstreet WILL BE BACK!"

Nick Carter tweeted, "Waiting and praying for our fans that were injured. If we can perform we're ready to go. But safety is first."

The boy band also took to Instagram to make a statement.
