Hi-tech facial recognition equipment will be used at this year's V music festival in a bid to ensure the safety of fans and weed out troublemakers.
All 130,000 tickets to the festival sold out in March
Police at the festival in Weston Park, Staffordshire, will use an intelligence database linked to CCTV cameras to scan the site and return facial matches.
"The safety of V Festival fans is of utmost importance to us," said V Festival organiser Andy Redhead.
The two-centre festival in Essex and Staffordshire runs from 20-21 August.
"This year's Staffordshire V Festival will be the biggest yet, with over 70,000 people set to attend," said Chief Inspector Jon Drake, from Staffordshire Police.
Crooner Christie will be among the stars at the annual event
"Violence of any kind will not be tolerated. A small minority of offenders will not be allowed to spoil the weekend for the tens of thousands of law-abiding music fans."
The event takes place at Hylands Park, Chelmsford, Essex and Weston Park, Staffordshire, with bands playing both sites over the weekend.
Oasis, Franz Ferdinand and the Scissor Sisters will play at the event later this month. All 130,000 tickets are now sold out.
Other acts booked for the festival, now celebrating its 10th year, include The Prodigy, Athlete, Joss Stone, Kaiser Chiefs and veteran crooner Tony Christie.
