David Ungi was arrested in possession of a loaded gun at a gym in Spain seven years after he fled the UK.
The 31-year-old is currently standing trial at Liverpool Crown Court accused of murdering Vinny Waddington. The teenager was fatally blasted in the chest with a shotgun in 2015 after a crash on Banks Road in Garston.
Jurors heard at the close of the prosecution's case this morning, Wednesday, that Ungi left the country on July 15 2015. This was the day after 18-year-old Mr Waddington was shot dead.
