Radical Belgian Muslims disrupted a debate on Wednesday evening about Islam which featured writer and Muslim activist Irshad Manji and Green Left Party MP Tofik Dibi.
The Islamists threatened and spat on Ms Manji. Tofik Dibi, who accompanied Ms Manji to the police station where she filed a report, said that "the disruption of the debate shows that even in the Netherlands it is necessary to continue the debate on a free and moderate Islam."
Eventually, the police were called in to remove the protestors. A police spokesperson later said that two of the 22 men involved were arrested, one for making threats and one for insulting police.
