Police are appealing for information after a woman was allegedly sexually assaulted at a Harry Styles concert in Manchester.

The woman was approached from behind by a man who is said to have then sexually assaulted her at the Old Trafford Cricket Ground at around 8.30pm on June 15 of last year, Greater Manchester Police said in a statement.

“We will continue to investigate and we are asking anyone with any information to please get in touch with us.”
