George Floyd death: Journalist chased through London in third live incident involving Aussie media

A journalist and cameraman have been chased through the streets of London by protesters in a third incident involving Australian media in three days.

Nine News Europe Correspondent Ben Avery was reporting on the riots in the UK which started after US man George Floyd died after a police officer knelt on his neck for eight minutes.

Avery was speaking live on Australian breakfast show Today on Thursday near the Houses of Parliament when they were ambushed by protesters.

"A bit of a clash with us here at the moment," Avery can be heard saying before fleeing the scene with cameraman Cade Thompson.

"OK, guys. What's happened, we've been trying to walk away from the danger here. It's been following us," he said.

Today presenters Karl Stefanovic and Allison Langdon said the incident showed "how dangerous it is for our reporters, for all journalists on the street at the moment trying to cover these riots when emotions are running so high". 

After the incident Avery told Today "it was a bit of a shock", Nine News reported.

"We were getting a little bit of grief from one or two in particular who took exception to us being there," he said.

"As soon as we started to go on air you see Cade's camera starts to tilt down because they are pulling his camera down.

"Then we saw someone come off to the side and take my microphone out of my hand and there was a group of dozens of these protesters just chasing after us down the road."

Avery said he and Thompson "bolted" to where a large group of police were standing.

"We realised that our security guard was still in amongst all of that crowd. He was taking on about, I think, 15 people at one stage. We didn't want to run off too far because he was still there," he said, Nine News reported.

He said the police officers were very outnumbered by the protesters, meaning there was not much they could do.

Avery said that even with a security guard, "we felt quite unsafe".

"It was pretty scary really. You can only imagine what it's like in the US at the moment where they are dealing with this all the time."

The ambush came only hours after another of Nine News correspondents Sophie Walsh was attacked while live on air from London.

Walsh was speaking during a live cross when she suddenly began screaming and swearing over rolling footage.

"Sorry, sorry, sorry. I just... I just had someone come up and try and... yeah. Sorry. Yeah, yeah. A man just came up and grabbed me. He is okay. He is not armed. A man just came up and grabbed me though."

She said the man made stabbing motions at her and was detained by bystanders until the police arrived and arrested him.

The first incident involving Australian media occurred on Tuesday in Washington DC when a 7News team was turned on by police while covering Donald Trump's national address.

The camera operator was bashed with a riot shield and his equipment was punched by police while journalist Amelia Brace was hit with a baton.
