Sir Philip Green has been charged with four counts of misdemeanour assault in the United States.
A pilates instructor, Katie Surridge, alleges the retail tycoon, 67, touched her inappropriately, Pima County Attorney’s Office said.
She told police in Arizona it happened during classes at the Canyon Ranch luxury resort in Tucson in 2016 and 2018.
He has been charged with four counts of knowingly touching another person with the intent to injure, insult, or provoke.
Deputy county attorney Lauren Deakin said: “Philip Green has been formally charged with four misdemeanour assault counts.
“These are class three misdemeanours. Each count has a potential sentence of up to 30 days in the Pima County jail, a fine of not more than $500, and up to one year of probation.”
Ms Deakin said an arraignment date had been set for 19 June.
Sir Philip has previously denied the allegations, which were investigated by the Pima County Sheriff’s Department.
It emerged earlier that pensions watchdogs are demanding that Sir Philip hands another £50m to the retirement scheme of his Arcadia retail empire to avert its collapse next week.
Sky News has learnt that The Pensions Regulator (TPR) has told Sir Philip and his advisers that it wants him to contribute the £50m on top of an existing proposal from his family to inject £100m into the Arcadia pension fund.
