Um, guys you're not in China where this behavior is rewarded. It's one of those little cultural differences that the guide books don't always explain. How's anyone supposed to know that in a foreign democracy, you can't harass a member of parliament including pushing and ripping the flag of Tibet out of their hands? Doing it to the leader of a political party makes it even stickier but let's hope it's a lesson learned and the friends at home will provide a "welcome home" gift.
Part of the investigation will include speaking with witnesses, viewing pictorial coverage and liaising with the Speaker of the House, who gives permission for lawful protests to take place in Parliament's grounds, police say.
Dr Norman is outraged that members of a Chinese delegation were able to push him, hit him with an umbrella and rip a Tibetan flag from his grasp.
He was protesting as Chinese Vice President Xi Jinpin arrived at Parliament greeted by a few dozen pro-China supporters.
Some of the group, believed to be Chinese security, took exception to Dr Norman waving a Tibetan flag and calling for democracy.
The MP brushed away attempts to have an umbrella placed in front of him, then clashed with security guards as they pulled the flag from his grasp and threw it on the ground.
He yelled they could suppress freedom of speech in China, but not in New Zealand.
