Actor Hugh Sheridan has taken to Instagram to reveal that his Hair castmate Matthew Manahan and his brother were victims of a violent street attack in Perth overnight.

Sharing a picture of himself with Manahan, he wrote:

“Tonight this kind soul pictured here with me was attacked for no reason, he was glassed in the street. Minutes later my beautiful brother was attacked by the same person just after leaving the theatre with me.”

He continued:

“I’ve just got back from the police station in North Bridge, I witnessed another senseless attack where people were spat on because of their race and a boy and his girlfriend were punched, I’m in shock, I’d never seen someone so aggressive and so fast, he had no motive and chose the sweetest people I know to hurt.”

Tonight this kind soul pictured here with me was attacked for no reason, he was glassed in the street. Minutes later my beautiful brother was attacked by the same person just after leaving the theatre with me. I’ve just got back from the police station in North Bridge, I witnessed another senseless attack where people were spat on because of their race and a boy and his girlfriend were punched, I’m in shock, I’d never seen someone so aggressive and so fast, he had no motive and chose the sweetest people I know to hurt. The story we’re trying to tell in Hair is exactly about this kind of action, why all the fighting? Why the need for senseless violence? I don’t know what will happen for opening night tomorrow, Matt is still in hospital and my understanding is he’s still awaiting a cat scan, I thought it’s better to let you know now before I try and sleep so if you’re coming tomorrow you have a chance to get information. I can tell you now, our amazing tribe have rallied around each other and these events only bring us closer together, it only shows how relevant our story still is and how timely it is for it to be told. If my brother wasn’t there I would’ve been completely caught unaware and both Matt and myself would be in hospital. We will endeavor to run the show as planned as long as it is safe to do so, the show goes on always, with added meaning and reason, can’t actually believe tonight happened. “What a piece of work is man, How noble in reason, how infinite in faculty, In form and moving how express and admirable, In action how like an Angel, In apprehension how like a god, The beauty of the world, The paragon of animals. And yet to me, what is this quintessence of dust? Man delights not me; no, nor Woman neither; though by your smiling you seem to say so.” Hamlet and Hair. Love and no harm to all of you tonight, H x

Hugh Sheridan is starring in Hair alongside Manahan, Prinnie Stevens and Paulini of Australian Idol fame.

Sheridan said he was unsure if matinee and evening performances of the show would go ahead today, with Manahan in hospital awaiting a CAT scan, but organisers say they will continue as scheduled.

Per ABC News, two boys, aged 14 and 15, have been charged over several alleged assaults, including one in which a man aged in his 20s was hit on the head by a glass bottle.

They are due to face court today.
