UPDATE: Two teenage boys have been charged over an attack on Hugh Sheridan’s brother and castmate outside a theatre in Perth last night.

The actor, who is currently appearing in the musical HAIR, revealed in an emotional social media post that his castmate Matthew Manahan was “glassed in the street” during an apparent random attack.

Sheridan said his brother was also targeted by the same man as the group left the venue.

“Tonight this kind soul pictured here with me was attacked for no reason, he was glassed in the street,” Sheridan wrote.

“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.”

Police said the first incident occurred about 10.30pm near the intersection of Murray and Barrack Streets, closely followed by an attack near the intersection of Hay and William Street and along Hay Street Mall.

Police arrested and charged a 14-year-old-boy from Swan View with aggravated assault occasioning bodily harm, common assault in circumstances of aggravation, disorderly behaviour and possession of stolen property in relation to the incidents.

A 15-year-old from Northam was also charged with two counts of common assault in circumstances of aggravation, carrying an article with intent to cause fear, disorderly behaviour and possession of stolen property.

Both are due to appear in the Perth Children’s Court today.

Sheridan, a three-time Logie winner, described the two victims as “the sweetest people” and said he was in shock over the “aggressive” and “fast” attacks.

“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,” Sheridan said.

“If my brother wasn’t there I would’ve been completely caught unaware and both Matt and myself would be in hospital”.

“I can tell you now, our amazing tribe have rallied around each other and these events only bring us closer together.”

The 34-year-old is top billing alongside singer Paulini in the musical’s 50th anniversary production which will tour Australian stages until October.
