Ethical concerns over Mahmood's scoop

Reading the latest "exclusive" by Mazher Mahmood I had an even more queasy feeling than usual when confronted by his stories. It boasted: "News of the World delivers 66 on-the-run foreigners to Home Office to show how easy it is". The article claimed that "undercover reporters" had "rounded up" a number of "illegals" in London under the pretence that they were being driven to a building site. Instead Mahmood delivered them to the Colnbrook Immigration Detention Centre where 25 police were waiting to arrest them. It appears that I'm not alone in viewing this as a highly suspect operation. Apart from the outrage of the people involved - see my alert below - some solicitors believe they are victims of false imprisonment or even kidnapping. I can put concerned people in touch with an organisation that might be able to help. Apart from that, am I alone in worrying over the ethics of this journalistic exercise by the fake sheikh?
