A man has been charged with throwing a coin which hit referee Mike Dean during Sunday's clash between fierce south Wales rivals Cardiff City and Swansea City.
The incident came in the 42nd minute of the Championship clash at Ninian Park, in what was the final meeting between the two sides at the famous stadium which Cardiff will leave at the end of the season.
Dean was left bleeding from a cut above his right eye and needed medical treatment for the injury he suffered in the 2-2 draw.
On Monday, South Wales Police confirmed a 24-year-old man from Pontypridd had been charged in connection with a missile throwing incident. He was released on bail to appear at Cardiff Magistrates Court on April 20.
After the match, police made six other arrests, five relating to public order offences and one for breaching a football banning order. Of those involved, three were from Cardiff, one from Ebbw Vale, one from Blackwood and one from Abertillery.
The Football Association of Wales have confirmed they are investigating the coin-throwing incident that marred the derby.
Cardiff, who have been plagued by a hooligan reputation in the past, could now face further reprimand from the FAW, although the association have refused to put a timescale on when a decision will be made.
