THE killer of a Nottingham police officer is back in jail after beating up his girlfriend in Lincoln less than three months after being let out.
David Parfitt was locked up for 12 years in 2003 for the manslaughter of PC Ged Walker in Bulwell.
Dog handler PC Walker, 42, suffered head injuries trying to stop Parfitt driving off in a stolen taxi in St Alban's Road.
The officer, who had more than 20 years' service, died two days later.
Parfitt, now 35, was released on licence in March and was staying at a hostel in Lincoln.
In May he punched and head butted his new partner, from Lincoln, who he met online.
Parfitt was given a two-year jail sentence at Leicester Crown Court yesterday for actual bodily harm and six months for attempting to pervert the course of justice, to run consecutively.
After the sentence Lincolnshire Police spokesman Dick Holmes said: "He had told this woman about his past but was convincing when he said his life had changed and he had turned himself around.
"When he is in drink he becomes a violent individual and a nasty piece of work."
Parfitt denied the new offences after he was charged by Lincolnshire Police. But he was convicted in August after a jury found him guilty at Lincoln Crown Court.
Notts Police Federation chairman Phil Matthews said: "We think he should have got longer in the first place. The fact that he's been given parole and abused that speaks for itself.
"It is good news that he is back in prison and hopefully he will now serve the rest of his sentence."
Parfitt, then of Wareham Close, Aspley, was also on licence from prison after being released early from a robbery sentence when he killed PC Walker.
He was found guilty of the killing in December 2003 at Birmingham Crown Court and sentenced to 12 years plus an extra year for driving offences.
The death of PC Walker shocked Notts and the force in January 2003. He was the first Notts officer to die in the line of duty since 1978 and a commemorative stone lies close to the spot where he fell.
The annual Ged Walker Memorial Dog Show was set up in his honour and is held every summer in Long Eaton.
This year's event in September attracted hundreds of people and overall the show has raised a total of around £8,000 for good causes in PC Walker's memory.
