Asylum seekers at South Australia's Woomera Detention Centre have ended their peaceful protest against an alleged attack on their religion.
A spokesman for the Immigration Department says investigations have already begun into the alleged incident.
Asem Judeh of Melbourne says he was contacted three times today by the one of the men involved in the protest.
Mr Judeh, who chairs the Palestinian Refugee and Exile Awareness Organisation, says the group has begun a chant, following a claim that one of the centre's security officers threw and stood on a copy of the Koran, belonging to a detainee.
He says if the claims are true, it is an example of how asylum seekers are being forced to protest, because of acts of humiliation.
"What they are doing, they are gathered in one place and chanting, 'God is great, God is great', and they have a loud tape recorder with...part of the Holy Koran," Mr Judeh said.
Mr Judeh has called for a full investigation into the alleged incident.
