A recent convert to Islam has allegedly been set upon by fellow Muslims, who took it into their own hands to flog him with a chord 40 times for drinking alcohol.

The three Muslim men involved in the act, allegedly burst into the bedroom of their newly converted Islamic brother, and held down their victim, while a fourth handed out the punishment.

Ibrahim Siddiq-Conlon is a former catholic from Adelaide, now the founder and self appointed leader of an extremist Muslim party called Sharia for Australia.

“There are always a few people who will get very strange ideas, and are quite happy to expend them in public, even though they have no authority, and have right to speak on behalf of the community," said author Jamila Hussain.

Diaa Mohamed is an organiser of the Islamic group, My Peace and believes that “even in an Islamic state there's a process - a judicial process, and you are innocent until an Islamic court finds you guilty. But we are not in an Islamic state, and something like this should not happen."

“I've been on the phone and spoken to a lot of Islamic leaders and Imams, and they're unanimous that happened is absolutely not in accordance, nor condoned, by Islam, or any of the Imams here," aid Diaa.

The men allegedly involved in the vigilante attack are in their late teens and early 20s, and have now appeared in court.
