Modupe Idowu, 59, and her friend Esther Jubril Badmos, 48, were arrested after becoming embroiled in a dispute at a shoe shop in the city of Guangzhou.
They were locked up in 'hell-like' conditions at a detention centre for 38 days and although they have now been released, the two women remain trapped in the country as their visas have expired and authorities refuse to issue them new ones.
