A warning has been issued to fans headed to watch a 1D charity football challenge urging them to devise a back-up plan in case their mobile phone runs out of charge.
Police in Leicester have been liaising with organisers of similar events- and said one of the major problems has been people draining their phones of battery by taking pictures and posting them online.
This means they have no way of contacting friends or family if they get separated or when arranging travel home.
Officers are advising people to write down important contact details on a piece of paper, so if their phone dies they can still call their loved ones.
One Direction stars Niall Horan, Liam Payne and Louis Tomlinson will be in the Midlands today for the Niall Horan Charity Football Challenge. They will be joined by Olly Murs, Rod Stewart, and Robbie Fowler at Leicester's King Power Stadium.
Doncaster's One Drection star Louis Thomlinson will help out his band mate Niall in a charity football match this afternoon. Niall will manage the team, which also includes Olly Murs and Rod Stewart, to raise money for Irish Autism Action and UK Heart and Minds.
He is more used to wowing the crowds on stage but One Direction's Louis Tomlinson did the same on the football pitch last night in his long-awaited debut for Doncaster Rovers.

This One Direction Fan was at the Keepmoat tonight to see Louis Tomlinson's debut for the Rovers, but her journey to get there was at a little longer than most others who had turned out to see their idol.
She had travelled from America for the occasion and although the match ended with a goalless draw, she got to see Louis on the pitch in the second half.
As a global superstar and a recent winner at the Brit Awards, he's used to rubbing shoulders with the rich and famous.
But tonight Louis Tomlinson isn't taking centre stage.
The One Direction star is finally making his debut for Doncaster Rovers tonight - his home team. He's playing in the South Yorkshire derby and hoping to raise lots of money for charity. Michael Billington reports.
