A British law student jailed for life in a hellhole Dubai prison had only taken a single line of cocaine when she was arrested, her former cellmate has claimed.

Mia O'Brien, 24, of Huyton, Merseyside, was sentenced to 25 years behind bars after a day-long hearing which was held entirely in Arabic on July 25.

She had been caught by Middle Eastern police at a party last October with 50 grams of the Class A drug, which has an estimated street value of around £2,500 in the UK.

The Liverpool University student pleaded not guilty to drug offences but was convicted by a judge after just one day in court, where she was also ordered to pay a fine of £100,000 for the crime.

Mia had spent months in the Al Barsha police detention centre before being ordered to languish in Dubai Central Prison - also known as Al Awir - which has been dubbed 'the Middle East's Alcatraz'.
