Footage plea after violence at Cardiff Gaza rally
Police are seeking video footage of violence which broke out during a protest march in Cardiff opposing Israel's military action in Gaza.
Bar stools and glasses were thrown as 1,500 people took part in the rally on Mill Lane, on Saturday.
Two men who were not involved in the rally were arrested and South Wales Police defended claims policing of the march was poor.
It said it was reviewing evidence to understand how the violence started.
Chief Inspector Dan Howe said the "alarming and violent" incident was isolated and was not representative of the whole event.
He said the violence that occurred was an exceptional occurrence, but was one that needed to be examined.
"The actions of the individuals involved will not be tolerated and officers are currently reviewing evidence in order to bring those offenders to justice," he said.
"Cardiff has a strong record as a safe city and we want to uphold that".
His comments came after Cardiff South and Penarth MP Stephen Doughty and Newport councillor Majid Rahman, who both took part in the rally, raised concerns over the policing of the event.
After the march a man, 22, from Caerphilly, was arrested on suspicion of assault and a 33-year-old man from Pontypridd for affray.
Both have been bailed pending further inquiries.
