One of the policemen who participated in the assaults on the London G20 protesters had earlier posted to his facebook that he couldn't "wait to bash some long haired hippys."

The police officer's profile page on social networking site Facebook contained a message apparently written by Pc Ward at 2017 BST on 1 April.

It stated: "Rob Ward can't wait to bash some long haired hippys up @ the G20."

Twenty minutes later another Facebook user posted a reply that said: "Dats bad but good in da same way lol [laugh out loud]."
