Fans stage protest against use of facial recognition technology ahead of Cardiff v Swansea match

Football fans and human rights groups have taken part in a protest against the use of facial recognition technology in Cardiff during the South Wales derby.

South Wales Police faced criticism over a decision to use the technology with fans and rights campaigners saying it is, ''a step too far.''

Police used the surveillance technology last October at another match between the two sides, attracting protests from fans.

''I think we're all being treated as criminals,'' one masked protester said.

Campaign group Big Brother Watch described the surveillance technology as ''a waste of public money.''
