Hi, what are our rights concerning actually stopping people to smoke in a smoke-free/restricted area?

Lets take public toilets for an example. Smoking in public toilet is prohibited under the Control of Tobacco Product Regulations of 2004 Regulation 11(1)©...
If is see someone smoking, what can I do legally to stop him from smoking if he doesn't comply when I ask him to put it out? Take a picture? Police report??

I've no problem defending myself and 'getting violent' if the situation call for it. It's just that it seems unclear how the laws are being enforced and what our rights are concerning the fact that it's a law being broken. It's especially important since smoking is a serious health hazard to the people in vicinity of the smoker.

Also, any known incident where the police actually take action on reports? I'm thinking highly unlikely, unless the guy smokes in a kindergarten in front of small children...
