'Too scared' to run away

Anna was brought to Glasgow and forced to work as a prostitute

At the age of 12, Anna's parents died and she and her younger siblings were looked after by their grandmother in a Nigerian village.

She went to work for a family her grandmother trusted as a domestic, but was sexually abused by the father of the household.

He told her that if anyone found out, her grandmother would die of shame and that he would kill her and her siblings.

At 15, Anna ran away and, too ashamed to go home, she became a prostitute to survive, working in a restaurant that had rooms in the back where men would pay to have sex.

An Amnesty International spokesman said: "Anna had to take part in a ritual oath to make her more attractive to men and which bound her to the brothel.

Because Anna was very frightened and desperate she agreed to go Amnesty International spokesman

"She was told that if she ran away or told anyone she would be killed."

She was often violently abused by the men who paid for sex but was introduced to an English man who told her he could get her away from the city for a substantial amount of money.

The spokesman added: "Anna was told she would pay him back through prostitution, but that where she was going she would make much more money and the debt would be paid back quickly.

"Because Anna was very frightened and desperate she agreed to go."

Anna's travel documents were arranged but, after going through passport control, the man took her documentation. This was when Anna discovered she was in the UK.

From London they took a bus to Glasgow where Anna was taken to a flat where there were other women.

No passports

Anna was told she still owed a lot of money and was immediately made to work as a prostitute.

Men came to the flat at different times during the day and night.

Along with the other women, Anna was allowed out to the shops, but they were too scared to run away as they had no passports, no money and had been told that, as prostitutes, they were there illegally and would be deported.

Anna finally escaped and was picked up by police and questioned by immigration officials.

As she had no travel documentation and was in the country illegally, she ended up at Dungavel detention centre.
