British Member of Parliament Mike Freer says he was forced to hide behind a locked door and wait for police during a constituency meeting at a mosque Friday. Members of the radical organization "Muslims against Crusades" had advocated targeting Freer over his outspoken friendship toward Israel and vocal concern about the safety of MPs following the stabbing of a colleague.

Protests confronted Freer prior to meeting with constituents at a north London mosque on Friday afternoon. Concerns for his safety were heightened when 12 people forced their way inside. One of them called him a "Jewish homosexual pig," while others threatened him "as a member of the Conservative Party" and said that "had the blood of thousands of Muslims on his hands."

Freer is a member of "Conservative Friends of Israel," and drew ire over a post on his website in protest over the stabbing of an MP colleague by Islamist terrorist Roshonara Choudhry. The attack on MP Stephen Timms should serve as a "piercing reminder" to politicians that "their presence is no longer welcome in any Muslim area," Freer wrote. Protesters were also upset that he campaigned against a UK visit by radical cleric Raed Salah. Salah was arrested after entering the country due to a ban imposed on him by the Home Office because of his "virulent anti-Semitism."

Following Friday's incident, MP Freer called for an investigation into "Muslims against Crusades."

"What I'm saying is the Home Office needs to be continuing to monitor this group and as soon as they overstep the mark then the full force of the law should come down on them," he stated to members of the press. The group's website has been hacked and continues to be inaccessible.
