LONDON - The British police on Thursday started an investigation of the posters in South London issuing a fatwa against Home Secretary Theresa May. The London Metropolitan Police are seeking the source of the Wild West-style posters, which claim the fatwa has been issued 'for the abduction, kidnapping and false imprisonment of various radical clerics. The posters appeared at the same time as the Home Secretary announced in Parliament on Wednesday controversial reforms of control orders for terrorism suspects. A link on the posters directs people to a website which states: 'The current reality of Muslims living in Britain has unfortunately become very bleak; what was initially perceived by some, to be a malicious smear campaign against the Muslim community has now turned into something far more sinister. Subsequently, as a response to this extremely critical situation and having been left with no other alternative, a Fatwa has been launched against the Britains head of internal affairs and national security, Theresa May. 'We understand the seriousness of this religious verdict, and will be releasing further information in due course. The website specifies high-profile Muslims such as Khalid al Fawwaz, 48, a Saudi Arabian with links to Osama Bin Laden who is currently fighting extradition to the US on allegations of terrorism. It also defended renowned cleric Sheikh Abu Hamza who is detained while awaiting extradition to the US, and Abu Qatadah - 'a loving father and an ailing elderly man. The group which issued the posters, Theresamayfatwa.com, said it is planning to hold a press conference in Central London next week to explain the details of the fatwa. Abu Bakr, a 27-year-old adult learning teacher and spokesman for the group, denied the fatwa was a physical threat against the Home Secretary. He said: 'Perhaps 10 years ago people were confused about what a fatwa is but now so many have been issued that I think most people realise what they are. 'A fatwa is an answer to a question, and it could relate to a political question or even a marital problem. The contents of the fatwa cant be revealed until the press conference. But we have Muslims such as Khalid al Fawwaz who have been held in prison for 12 years without charge or evidence against them. 'What we want to do is ask Muslims if a situation like this is allowed in Islam? Should we vote for someone like Theresa May and what relationship should we have with a government like this. 'For someone like Abu Hamza there doesnt seem to be any hope for them, even though they are not accused of any crimes. 'Secret evidence is used against them in these situations and there seems to be one rule for Muslims and another rule for others. 'We are not really an organisation as such, more of a community group that has come together to raise questions about these issues because something needs to be done about it. The posters have been spotted on phone boxes, bus shelters and walls in Londons area of Balham and Tooting and are being treated 'as graffiti by Wandsworth Council, which is treating them with a no tolerance policy. 'As soon as we see them or they are reported they will come down. said a spokesman for the council. 'We urge residents if they see them go up again somewhere else to let us know and we will get rid of them.a
