A teenager arrested following an incident in which West Brom's Chris Brunt was struck in the face by a coin has been cautioned.
Thames Valley Police made an arrest in February after Northern Ireland international Brunt (31) suffered a cut under his eye when he approached the stand housing Baggies supporters following a 3-1 loss to Reading in the FA Cup.
The force has now said a 17-year-old has been given a caution in relation to the matter at the Madejski Stadium.
In a statement published on BBC Sport's website, a spokesperson for Thames Valley Police added: "A 17-year-old boy has been given a youth caution for using threatening or abusive words or behaviour or disorderly behaviour, likely to cause harassment, alarm or distress. No further action was taken in relation to throwing a missile."
The Football Association had also launched an investigation into the incident involving Brunt, who called the act "absolutely disgusting".
