The Metropolitan Police has faced a backlash from London mayor Sadiq Khan after it arrested an alleged rape victim over her immigration status.

The unnamed woman, in her 20s, attended a police station in London to report being kidnapped and abused during time she spent in Germany, before arriving in the UK.

While giving a victim statement, she told officers she had entered Britain illegally before being taken to a centre for rape survivors.

She was then arrested on suspicion of illegal entry into the UK and taken into custody.
