People who falsely applied for free tickets to Sunday’s One Love Manchester concert featuring Ariana Grande could be investigated by the police.

Ticketmaster set aside free tickets for the 14,200 people who were at last month’s Manchester Arena concert which ended in tragedy when a terrorist killed 22 people.

However, more than 25,000 people applied for the tickets to the all-star concert at the Emirates Old Trafford.

A chief superintendent at Greater Manchester police said the force was working with Ticketmaster to see what action could be brought against some of the 10,000 people who made “unscrupulous applications”, the Daily Mirror reported.

While it is unclear what offence the claimants had committed, Stuart Ellison said: “That is a matter we are exploring with the promoter. These lines are being worked through with the promoter.”

In a statement released today, Ticketmaster said 50,000 people attended the event, with more than £10m ($12.9m/€11.4m) having been raised for an appeal to raise money for the victims and their families.

Ticketmaster said: “All net ticket proceeds go directly to the We Love Manchester Emergency Fund, which was set up by the Manchester City Council in partnership with the British Red Cross, in aid of grieving families and victims of the horrific attack.”

The event was held at Emirates Old Trafford, which announced its presence on the global live music scene through hosting the concert, despite more than 70,000 football fans also attending the Michael Carrick testimonial match nearby at Manchester United’s Old Trafford just hours before.

Emirates Old Trafford is the home of Lancashire County Cricket Club and will later this year host a Test match between England and South Africa. It has previously staged concerts by the likes of REM, Oasis, Take That and Beyonce.
