This past week, apparently, two ministers found out first-hand that what the Bishop claimed was true:

The preachers, both ministers in Birmingham, were handing out leaflets on Alum Rock Road in February when they started talking to four Asian youths.

A police community support officer (PCSO) interrupted the conversation and began questioning the ministers about their beliefs.

They said when the officer realised they were American, although both have lived in Britain for many years, he launched a tirade against President Bush and the wars in Iraq and Afghanistan.

Mr Cunningham said: "I told him that this had nothing to do with the gospel we were preaching but he became very aggressive.

"He said we were in a Muslim area and were not allowed to spread our Christian message. He said we were committing a hate crime by telling the youths to leave Islam and said that he was going to take us to the police station."

The preacher refused to give the PCSO his address because he felt the officer's manner was "threatening and intimidating".

The ministers claim he also advised them not to return to the area. As he walked away, the PCSO said: "You have been warned. If you come back here and get beaten up, well you have been warned".

West Midlands Police, who refused to apologise, said the incident had been "fully investigated" and the officer would be given training in understanding hate crime and communication.
