Thousands of One Direction fans could face being locked out of the upcoming stadium shows for safety reasons.

Fans under 16 with general admission standing tickets must have an adult with them to get into the shows, while no under 12s will be allowed onto the pitch standing area.

The restrictions, which were included in the terms and conditions during the ticket sale, were put in place by the promoter to ensure the safety of everyone attending the shows.

Sunderland Stadium of Light staff have issued a reminder in advance of the opening show of the tour to avoid disappointment and confusion on the day.

The world’s biggest boyband kick off the UK leg of their ‘Where We Are’ world tour on Wednesday May 28 at the home of Sunderland AFC, but many fans will be now left wondering if they will make it past the door.

The UK leg of the tour also takes in Wembley Stadium, Ethiad stadium in Manchester and Murrayfield in Edinburgh, which have the same age restrictions.

The age restrictions will be strictly enforced on the day by safety stewards and admissions staff and concert-goers are advised to carry some form of identification, such as a photocopy of a passport or birth certificate, if they appear younger than they actually are.

Anyone who has purchased a ticket for pitch general standing area for a child under the age of 12 are being advised to contact their booking agent immediately, as they will not be allowed to enter the stadium.

Other restrictions include:

– Anyone aged under 12 must have a seated ticket and be accompanied by an adult aged 18 or over.

– Concert-goers are also strongly advised against bringing children aged under five years of age to a large scale concert such as this.

According to a club spokesman one adult can accompany up to seven children, however parents and guardians are advised to pay careful attention to this depending on the age and needs of the children involved.

Sunderland AFC’s head of safety and security, Paul Weir, said: “The age restrictions are laid down by the promoter to ensure the safety of everyone attending the show, which is a very different dynamic to anything we have staged at the Stadium of Light previously.

“The general admission pitch standing area is not a suitable environment for under 12s and anyone who doesn’t meet the age requirements will not be allowed to enter the stadium. We would advise fans to check their tickets carefully in advance to avoid any issues on the day.”

Sunderland AFC would also like to advise those attending the show that the ‘Challenge 25’ protocol will be in place. This means that anyone who appears to be under the age of 25 will be asked for identification when purchasing alcohol.
