PETALING JAYA - The couple implicated in the slavery case of three women in London, Britain, had been previously arrested by the Metropolitan Police in the 1970s.
The BBC reported that the 67-year old couple were arrested for immigration offenses.
The Metropolitan police had said that there were no signs of the couple, believed to be married, were violent to others.
However Freedom Charity, the movement which aided in the rescue of the victims, found that the three rescued victims had been mentally and physically abused.
The couple, who were initially arrested, have been released on bail until January.
Netizens in the United Kingdom acknowledged the case and expressed disappointment on the revelation.
@americanoandrew questioned how such a heinous crime could have gone unnoticed in a bustling metropolis like London.
"Can not believe 3 woman have been found as slaves in south London. How can that go unnoticed in such a busy city in 21st century #shocking," he said.
Netizen Katie Kennedy however, said slavery was already rampant in the city.
"Why everyone is so shocked about the 3 people kept as slaves in london, are they that ignorant to reality haha? Its everywhere," she said,
@3BMTV tweeted, "There's some seriously sick people in this world, shocking!"
Reacting to the news, @Shaz_Horan said, "I am done with this whole world. disgusting."
Netizen William K. Wallace was puzzled at how the prime suspects in the slave story could have been offered bail.
"They keep people slaves for 30 yrs and get bail..." he tweeted.
Briton Fintan Cox said, "The death penalty should be considered for the couple who kept those slaves in London. They stole peoples lives & they should face the same."
