An investigation has begun into the alleged "inappropriate use" of a recently-opened £14m theatre in County Durham.
The loss-making Gala Theatre in Durham City, is already the subject of a vigorous financial review, after being taken into the hands of city councillors.
Now the Lib Dem-controlled city council has ordered an inquiry into allegations of unauthorised late-night parties at the riverside venue.
The Gala opened in January 2002 as the largest provincial venue in the UK in a decade.
The theatre, which also boasts a cinema, ran into difficulty within months when its original managers, the Entertainment Team, went into liquidation.
'Thorough investigation'
In its first year, the site lost £700,000 and Durham City Council, which is now running the venue, says it has been budgeted to lose a further £400,000.
Durham City Council leader Sue Pitts and deputy chief executive Brian Spears confirmed the internal investigation had started after reports of "inappropriate use" of the theatre's facilities.
Ms Pitts said: "We are taking these allegations very seriously indeed and we will launch a full and thorough investigation."
A spokesman for Durham City Council said: "An internal inquiry has commenced to investigate allegations that have been made concerning inappropriate uses of the Gala Theatre.
"The inquiry coincides with the commencement of an in-depth evaluation into available options for its future management.
"The study will focus on the day-to-day management, programming and future use of the complex."
