Manchester United striker Mason Greenwood will no longer face charges of attempted rape and assault.
The Crown Prosecution Service (CPS) said on Thursday that the charges, which also included controlling and coercive behaviour, had been dropped.
Greenwood was formally charged in October following an investigation that began in January 2022.
“In this case, the combination of the withdrawal of key witnesses and new material coming to light meant that there was no longer any realistic prospect of a conviction,” the CPS said in a statement. “Under these circumstances, we have a duty to stop the case.”
Greenwood was arrested in January 2022 after the images and videos were shared on social media.
The 21-year-old has been suspended by United and is not allowed to train with the squad. The club has not yet commented on the CPS decision.
Greater Manchester Police said they understood the reasons for the suspension of proceedings, but reaffirmed their “commitment to investigating allegations of violence against women and girls”.
“The investigative team has remained in regular contact with the legal team, providing all updates, and therefore I understand the reasons for stopping the proceedings at this stage and that this decision was not taken lightly,” said Chief Superintendent Michaela Kerr.
The Bradford-born player came through United’s academy and made his senior debut for the Red Devils in a Champions League win away to Paris St Germain in March 2019.
