Steve Wynn, boss of casino giant Wynn Resorts, has been hit with allegations of decades-long sexual harassment by multiple female staff members.

On Friday, Wynn Resorts’ stock shed nearly 10% of its value after the Wall Street Journal’s Alexandra Berzon reported on allegations detailing decades worth of sexual abuse by Steve Wynn against female staff at Wynn’s Las Vegas properties.

The allegations include a 2005 account by a manicurist at the Wynn Las Vegas resort who claims Steve forced her to have sex on a massage table he kept in his personal office. The manicurist ultimately reached a $7.5m settlement with Wynn over the incident.

A former massage therapist at the Wynn Las Vegas spa claimed Steve routinely exposed himself to her during massages, at one point ordering her to massage his penis to climax by saying “Don’t’ ignore it anymore.”
