Harrison, 38, has spent a year in Spain after being extradited to serve a four-year sentence for battery.
The fighter left Spain before his punishment was made public and had hoped the conviction would be quashed – without success.
A representative posted the following to confirm Harrison was now on home soil and able to see his family once again.
“Scott’s now back in Scotland. Happy to finally see Stacey and his kids after a year in Spain,” said a social media post.
Father Peter had been vocal in support of his son being able to serve out his sentence in the UK, which is expected to be at least another twelve months before the chance of release.
“Scott misses his family. There is no contact with his children — that’s a year he has been away because he’s a champion boxer,” said a concerned Peter last month.
Peter, who also trains his son, clarified that Harrison. nicknamed ‘The Real McCoy,’ had been staying shape whilst in prison and could be looking to fight again at some point in the future.
Following a previous stint behind bars, Harrison returned from a seven-year ring absence in 2012, winning two and losing one of his three comeback bouts.
