South Wales police have revealed that no further action will be taken over the clash between Eden Hazard and Swansea ballboy Charlie Morgan on Tuesday evening.
The Football Association charged the Belgian wideman with violent conduct on Friday afternoon for his part in the incident which took place during the Capital One Cup semi-final.
However, the 22-year-old will not face criminal charges from the authorities.
A tweet on the south Wales police force's official account read: "Swansea City ball boy incident update: We can confirm there is no longer any police involvement in this matter."
SMRT will embark on a full-scale inspection of the entire North-South and East-West lines to detect any potential rail cracks.
