Warriors co-owner Sir Owen Glenn has been accused of inappropriate behaviour towards several of the club's star players during an evening at an upmarket Viaduct restaurant.
The multi-millionaire asked three-star recruits, including Sam Tomkins and then head coach Matthew Elliott, to join him for a meal at Euro Restaurant in February.
Sir Owen is said to have encouraged the players to drink shots, days out from a major tournament, and was involved in other behaviour that concerned his high-profile guests.
Sir Owen disputes the version of events, saying he was the subject of a "witch-hunt". He said he offered the players a drink on arrival.
