A family of travellers forced some of the most vulnerable men in society to work for them on a site "like a concentration camp", Luton Crown Court has heard.
The Connors controlled and exploited dozens of homeless people, alcoholics and drug addicts for financial gain, verbally abusing and beating their victims, prosecutors said. One of their alleged victims claimed they treated him "like a slave", jurors were told.
The men were recruited from homeless centres or "simply off the streets" and made to carry out daily physical labour. One of the workers told police he regarded the site as "like a concentration camp".
