Police say four men and four women were found captive in a north Houston home, with some held up to a decade, according to a report.


CNN says the men are between 50 and 80 years old. The report adds that the women were said by police to have mental illness.


Police have detained one person for questioning, but no charges have been laid.


The report comes two months after three women were released from a home in Cleveland after being held a decade.


Earlier this month, Amanda Berry, Gina DeJesus and Michelle Knight turned to YouTube to thank the public for the encouragement and financial support that have helped them restart their lives since they were released in May.


The women had gone missing separately between 2002 and 2004, when they were 14, 16, and 20 years old.


Ariel Castro, a 52-year-old former bus drive, has pleaded not guilty to a 329-count indictment alleging he kidnapped the three off the streets and held them captive in his two-storey home. Castro is said to have fathered the six-year-old daughter with Berry.
