Lane Cove Theatre Company's production of Holding the Man has had a sold out season, but it appears not everyone is a fan of the show.
After last night's performance, 12 cast and audience members returned to their vehicles outside The Performance Space at Longeuville, to find their tyres had been slashed.
A police spokesperson said they would investigate "motives of bias" behind the attack.
It is not the first time the production, which tells the 15-year love story of two men, has been targeted.
