The statement came in response to last week's joint federal and state anti-terrorism operation, in which police raided a dozen properties across Melbourne, seizing computers, imitation firearms and registered firearms in the raids and laying terrorism-facilitation charges against a 23-year-old man.

The Age visited the al-Furqan centre last night. A member who came to the door declined a request for an interview. Instead he said any questions should be emailed. The man also declined to give his name.

In an email responding to questions from The Age, a centre spokesman stated the centre will make a decision on its legal options following advice and consultation with its community.

Police declined to comment on the five-page statement, in which al-Furqan claimed women had been asked to ''become spies for ASIO'' and were subjected to ''degrading treatment'' from ''increasingly rude'' police. The statement said police had damaged property and forced children to undress in front of them.

''Up to 30 armed police officers were seen raiding one house. The family inside this house consisted of six young children, aged between three and 14, and their frightened and confused mother; the father was overseas, and the police were aware of this fact.
