The Three Lions were victorious against the Danes on Wednesday following a 2-1 extra-time win but the match was not without controversy after their spectators reportedly behaved in an unsporting manner.
That stemmed from a penalty England had been awarded in the first half of extra-time when, with the scores delicately poised at 1-1, a fan shone a laser in the face of Denmark goalkeeper Kasper Schmeichel as Harry Kane was about to take the spot-kick.
The governing body has also charged England, who have reached their first major final since 1966, for interrupting Denmark's national anthem prior to kick-off with some incessant booing, and for lighting up fireworks.
"Disciplinary proceedings have been opened following the UEFA EURO 2020 semi-final match between England and Denmark (2-1), played on 7 July at Wembley Stadium, London," UEFA said in a statement.
"Charges against England:
- Use of laser pointer by its supporters - Article 16(2)(d) of the UEFA Disciplinary Regulations (DR)
- Disturbance caused by its supporters during the national anthem - Article 16(2)(g) DR
- Lighting of fireworks by its supporters - Article 16(2)(c) DR
"The case will be dealt with by the UEFA Control, Ethics and Disciplinary Body (CEDB) in due course."
