A man was attacked a ballet dancer from Bath on a disused canal towpath in Cardiff has had his sentence increased to 18 years.
28 year old Mohammed Ali Mohamoed was originally jailed for a total of 13 years for assaulting Jack Widdowson, who was 19 at the time.
Three appeal judges have unanimously ruled the sentence was inadequate because the trial judge wrongly thought Mohamoed, of Splott in Cardiff would be automatically deported on completing his sentence.
The Judges said Mohamoed could spend years resisting removal from the UK on the grounds that it would infringe his human rights.
His sentence has now been extended to 18 years to meet the danger Mohamoed could pose to the public if released from prison but not immediately deported.
Despite being badly injured in the attack in November 2011, Jack Widdowson has been able to return to the stage.
"Jack has made an amazing recovery from a horrific injury and we would like to thank the many people who have helped to achieve that" said his parents Julian and Celia.
"He has been performing for some time now and has already performed publicly on a number of occassions.""We and he are just delighted that he has been able to resume his career as a dancer despite what happened to him."
“Mohammed Ali Mohamoed carried out an appalling attack that left his innocent victim with potentially life threatening or life changing injuries" said Rhodri Thomas, District Crown Prosecutor for the Crown Prosecution Service.
“As a prosecution team, we have been heartened to learn of the speed and extent of Jack Widdowson’s physical recovery from his injuries, but this in no way detracts from the seriousness of the attack carried out by Mohamoed.
"Nor does it lessen the impact of Mohamoed’s actions on Jack and those close to him."
“Thankfully, Mohamoed has now been brought to justice for this despicable attack and we hope this will be of some comfort to Jack as he continues to rebuild his life.”
