Crystal Palace have vowed to step up security measures ahead of this weekend’s home date with Arsenal after the recent Newcastle and Liverpool games were marred by coin throwing from the stands.

CCTV footage from both games has already been passed on to the police by the club and now body cameras are set to be introduced for match stewards on a trial basis.

A new HD system is being introduced to give sharper images to the current CCTV system, which will produce images that have four times greater resolution.

There will also be more cameras installed, giving access to more angles, allowing operators to zoom in on specific sections of the ground. Stands will also be monitored from above and behind.

The club are also investigate the feasibility of using facial recognition technology to help identify culprits.

A Palace spokesman said: “We are taking a number of steps to ensure there is no repeat of the incidents that took place during the Newcastle and Liverpool matches.

“We want to continue to allow our fans to express themselves in a positive way, but are determined to catch any individual who risks ruining the enjoyment for everyone.”
