A former president of Floriana FC boxing promoter Stephen Vaughan was jailed for 15 months after he admitting to helping a man who killed a policeman flee justice, British media report.

Stephen Vaughan junior allowed his sister’s boyfriend Timmy Donovan to borrow his Mercedes, which he used to escape to Germany in the hours after the officer was killed.

The 31-year-old admitted perverting the course of justice by allowing Donovan to use his vehicle to “evade apprehension or prosecution by police”.

Judge Steven Everett said helping offenders escape from the authorities “strikes at the very root of our system of justice”.

PC Doyle, 36, was killed during a confrontation with football agent Andrew Taylor, 29, and sports event manager Donovan, 30, on a Christmas night out in Liverpool.

The off-duty policeman died after he was struck in Colquitt Street in the early hours of Friday, 19 December, 2014.

Henry Riding, prosecuting, told Liverpool Crown Court two men were arrested shortly afterwards - Taylor and Christopher Spendlove.

However, by the time Spendlove told officers Donovan had also been with them that night, the third suspect “had fled to mainland Europe”.

Donovan was not arrested until 21 January, 2015 at Dusseldorf airport in Germany.

It was not until 24 March - over three months after the incident - that he was finally extradited back home to stand trial.

He escaped by driving south to Folkestone, taking a crossing to Calais in France and then driving across mainland Europe.

Licenced boxing promoter Vaughan is an ex-footballer once on the books at Liverpool FC and Chester City, and former president of Maltese club Floriana FC.

Stephen Vaughan Jr. was appointed president of Floriana in January 2013. With this move, the Vaughan Boxing Promotions company also shifted toward boxing promotion in Malta. In February 2014, Vaughan resigned and was replaced as president by Riccardo Gaucci.
