Another member of the Rooney family is on trial accused of modern slavery.
45-year-old Joseph Rooney from Washingborough deliberately targeted victims who were homeless or alcoholics, Leicester Crown Court was told.
The court heard vulnerable men were forced to pave driveways for little or no money and live in squalid conditions.
Rooney denied one count of conspiracy to require persons to perform forced or compulsory labour and also denied three counts of causing actual bodily harm.
The prosecution claims he preyed upon five men and the offences are alleged to have taken place between 2010 and 2014.
The trial continues.
