The Metropolitan police stopped and searched Thomas after he gave a speech at a rally against the arms trade in 2007.
The police searched his shoulder bag and wallet for weapons, which they said could be used to cause criminal damage.
A police officer recorded on an official form that Thomas may have been carrying weapons as he had an "over-confident attitude". Nothing was found.
In January the European court of human rights ruled it was unlawful for police to use arbitrary stop-and-search powers against peace protesters and photographers under terrorism legislation. Kent police admitted conducting unlawful searches on 11-year-old twins and other activists at an environmental demonstration.
They detained him for 12 minutes, against his wishes without actually arresting him. Those who know the law (like me), know that is unlawful.
He has justed banked £1200 for being unlawfully imprisoned for 12 minutes by the Police.
Remember the golden words - "Are you detaining me?". I use them constantly when the Police want to have a quiet word with me (and they always do, can't think why). They HATE it. Unless you are committing a crime, the Police have no right to stop you going about your lawful business. Remind them as often as possible, unfortunately they need it.
Just for interest, another ploy they use with me is: "You are not allowed to protest here"
Simply reply "I'm not protesting, I'm walking around in a silly costume. Just like you in fact. Goodbye"
