She was imprisoned for cocaine smuggling along with Michaella McCollum
Drugs mule Melissa Reid has arrived back in the UK at Glasgow Airport, after spending nearly three years in prison in Peru.
The 22-year-old was jailed along with Northern Irish woman Michaella McCollum for trying to smuggle almost €2m worth of cocaine to Spain.
Ms McCollum from Co Tyrone was released in March, but has to stay on parole in the South American country.
Last month, a Peruvian court concluded that Reid has shown remorse for her crime.
She was released under a new Peruvian law which allows first-time drug offenders to walk free for good behaviour after completing a third of their sentence.
Janeth Sanchez, a spokeswoman for Peru's prison system, said: "(Reid) served her time in prison according to the law and can now go to her country, free, to the streets."
A UK Foreign Office spokeswoman said: "We continue to provide assistance to Melissa Reid and remain in contact with her family and local authorities."
McCollum insisted in a television interview earlier this year that she is a "good person".
The pair had claimed they were forced to board a flight with 24lbs of cocaine in food packets hidden inside their luggage, but later pleaded guilty to the charges against them.
Both were being held at the notorious Ancon 2 jail - where conditions are said to be cramped - with poor sanitation and toilet facilities.
Reid's father Billy has previously said the impact of his daughter's crime on his family had been "horrendous" and spoke in a video warning of the consequences of drug offences abroad.
About 90% of the 1,800 foreigners in Peru's prisons are awaiting trials for drug trafficking, or have been sentenced for such crimes.
