It is a fate experienced by Ope, 24,
who in 2005 met a man offering to help
her leave her life in Nigeria and find
employment abroad.
Her role, he said, would be as a nanny,
or in a factory. She did not realise she
would be forced into prostitution.
Following a treacherous four-day trip
by boat, with little food or water, she
arrived in Madrid, Spain, where she was
put to work on the streets.
But after becoming the victim of rape,
she was transferred to the UK by her
traffickers. "It was like I was a slave,"
she says, on the work forced upon her.
One day, while being allowed to buy
food in the market, she found a lost
wallet containing identification. Taking
money from her traffickers, she
decided to run away.
But when she boarded a train at King's
Cross St Pancras in London, Ope was
stopped by an immigration officer and
later sent to HMP Holloway.
While in prison, she was helped by the
Poppy Project charity, before she was
recognised by the court as a victim of
human trafficking.
All criminal charges against Ope have
now been dropped, but she may have to
return to Nigeria, where she fears
being re-trafficked.
Ope's name and some details of her
story have been changed for her own
protection.
