Ozark star Laura Linney watches in horror after NYFW event when crazed fan punches assistant

Horrified onlookers saw a crazed fan of Ozark star Laura Linney whack her young assistant in the head as she emerged from a show at New York Fashion Week.

The actress had enjoyed a front row seat at the Christian Siriano Fashion Show alongside Janet Jackson and Alicia Silverstone at the Pierre Hotel on the Upper East Side.

But things turned nasty as she waited outside among milling crowds afterwards for a car to pick her up.

A heavily-built fan with an autograph book tried to push past her assistant and reacted furiously when he could not reach the star, punching him in the back of the head before stalking off.

‘Oh my God!’ screamed one onlooker, ‘I have never seen anything like that.’

The four-time Emmy winner already looked nervous as she emerged from the show and glanced anxiously up and down the street.

‘It’s like chaos here, don’t worry we’ll figure it out,’ someone assures her.

The crazed fan is then seeing approaching from behind and poking her in the back with his pen, prompting the assistant to say ‘Hey hey! No, don’t do that’.

‘Don’t f***ing touch me’, the man responds, before lashing out at the slightly built assistant.

‘Are you alright?’ The Big C actress asks him as she lays her hand on his shoulder and the attacker storms off back towards the hotel.

‘Alright, I’m fine,’ he assures her and smiles as he shepherds her to the by now arrived car.

The video has been seen more than 1.3million times and many viewers were horrified at the vulnerability of celebrities at the event.

‘I’ve seen this guy so many times,’ wrote Lauren Chavez, ‘My office is across from rock center and he’s always waiting for the celebs to exit today show.’
