Two people have been charged on suspicion of servitude offences after four people were removed from an address in Dorset.
Mary Turner, 60, and David Porter, 63, from Wareham, were charged on Friday after first being arrested on suspicion of benefit fraud in February.
The alleged victims are British nationals aged between their late 30s and early 70s.
Police believe one of them may have been at the location for many years.
The arrests were made following an investigation and the execution of a search warrant.
The pair will appear at Weymouth Magistrates' Court on 6 October to face servitude and benefit fraud charges.
