British Muslim radical Anjem Choudary is one of the people behind the Sharia4Holland group and was present at Friday’s press conference in Amsterdam, the Parool reported on Tuesday.
Choudary, a former solicitor, runs the militant group Islam4UK which has been banned in Britain and has been involved in efforts to set up ‘sharia areas’ in parts of Britain.
He spoke briefly at the gathering in front of the war memorial on Dam square but did not say anything controversial, according to the AT5 coverage.
Sharia4Holland spokesman Abu Qasam was later arrested at his home in Woerden for making threats against MP and anti-Islam campaigner Geert Wilders. He was released but will face charges.
Justice minister Ivo Opstelten said on Tuesday there is a risk that supporters of the organisation, which is thought to have just a handful of members, could use violence.
‘There is a risk, I would emphasise that,’ Opstelten said in answer to questions from Wilders’ PVV party. The PVV wants the minister to ban the organisation but Opstelten says that is not possible because it does not formally exist.
