South Wales Police made only six arrests during this weekend's Cardiff vs Swansea derby, continuing a positive trend for the fixture.
There was still violence as fans in the eastern section of the Liberty Stadium had to be held back by officers, and a projectile was reportedly launched from the away end.
After Cardiff's 1-0 victory, some fans tried to cross the barriers separating the sets of supporters but were held back by police.
Considering the well-documented history of violence in the fixture, the six arrests, and five in the return fixture in November, signal a positive trend for police and security forces.
The police had drafted in officers from forces throughout Wales, and dogs and a helicopter were on duty.
British Transport Police guided about 16,500 home supporters to and from the stadium, as well as the buses carrying 1,800 Cardiff fans - which were isolated throughout the fixture.
The police played down the six arrests and praised the good behaviour of both sets of fans.
Superintendent Phil Davies, the match commander, said: "Rather than focus on the small number of arrests, I would like to thank the many thousands of fans who attended and witnessed an exciting derby match between these two great clubs.
"The partnership work between the management of the clubs, the work of their stewards and South Wales Police officers and the support of fans on the day made for an enjoyable afternoon."
