After 18 years on the run, an honor killing fugitive has admitted to murdering a factory worker who made a pass at his sister.

Tabraz Mohammed, 39, had learned 24-year-old Soheil Mumtaz had been making advances towards his sister, at the biscuit factory where they both worked.

He believed his family’s “honour” has been damaged and devised a plan to lure the 24-year-old to a meeting.

Mohammed, then 21, repeatedly hit Mr Mumtaz over the head with a hammer outside his home on Kenilworth Road, Luton, on April 4 2001.

He was left in a critical condition, but died five days later on April 9.

His killer then fled the country to New Jersey, in the United States, where he lived in secret for nearly two decades.

But in August this year, Mohammed was extradited from the United States.

The Bedfordshire, Cambridgeshire and Hertfordshire Major Crime Unit worked with the US authorities to carry out the extradition process.

He appeared at Luton Magistrates' Court on August 7 charged with murder.

During a brief hearing at the Old Bailey on Friday Mohammed pleaded guilty to murder and was told he would be sentenced on Tuesday 3 December.

Mohammed, whose last address was given as Southwood State Prison, New Jersey, appeared shaven headed in the dock.

He was remanded into custody to be sentenced on December 3 at St Albans Crown Court.

As he was led from the dock, there were angry shouts from the public gallery calling the defendant a "prick" and "son of a bitch".

Other high profile honour killing cases have shocked the UK in recent decades.

In 2003, Shafilea Ahmed, the 17-year-old British Pakistani girl from Bradford, was murdered by her parents in front of her siblings after she rejected a suitor.

It wasn’t until 2010 that Shafilea’s sister, Alesha, found the courage to speak out about she had seen.

Speaking at her parents trial Alesha told the jury: “I think I had just had enough.

“My state of mind was not very good at the time. I was living between two cultures and trying to please everyone.

"It was not me any more and I was doing things which were out of character - like turning to drink at university.

“I was not being myself any more and I just let it out. What happened to my sister had haunted me for a long time.”
