The move has been backed by Spain's Football Association RFEF, which has already given 18 prototypes to Spain's Police Intervention Unit UIP.

Their aim is to more easily identify aggressors whenever fights break out at Spanish stadiums as well as to assess the behaviour of police officers during altercations.

"It'll be an improvement in safety for everybody," a spokesperson for the UIP told Spanish news agency Europa Press.

Up to now, anti-riot cops at sporting events in Spain have had to carry handheld camcorders to monitor brawls, a method which left a lot of questions unanswered about who the main perpetrators were and if police had used the correct modus operandi.

Spain's anti-riot police have been under scrutiny in recent months for what a sector of Spanish society claims are excessively violent methods during the countless street protests the country is seeing.

Last Tuesday, a Barcelona judge ordered two Catalan anti-riot officers to testify before him after a woman claimed she lost an eye when a rubber bullet hit her during a November 14 demonstration.
