TORONTO, Aug 31: Another Pakistani, suspected of having ties to Al Qaeda, was arrested in here on Saturday raising the number of arrests to 20 this month, police sources said.

Immigration authorities declined to disclose the identity of the arrested person but the CBC television claimed that the man was a Pakistani student, in his 20s, and in Canada to study at the Ottawa Business College, whereas the investigators say that the college no longer exists.

Earlier, on Aug 14 police had arrested 18 Pakistanis and an Indian. Two of the Pakistanis were granted bail this week.

Human rights activists held a peaceful demonstration in downtown Toronto last week seeking the release of the Muslims.

On Monday, Pakistanis and Arabs will march together in Toronto’s Labour Day parade to demand the immediate release of the detainees. The theme of the protest will be “Being Pakistani is not a crime”.
