Man sought over alleyway 'honour killing' in Blackburn
Detectives have named a man they "urgently" want to speak to after a 24-year-old was stabbed to death in a suspected honour killing in Lancashire.
Naeem Majid Butt, 37, of Blackburn, is wanted by police after the body of Saheel Ahmed was found in an alleyway in the town on Tuesday.
It is believed Mr Ahmed had been chased by a man wielding a knife.
Officers also believe the attack may have been provoked by an alleged affair between the victim and a woman.
They are also looking at the theory that the murderer may have lain in wait before he carried out the revenge attack.
Police say Mr Butt has links to Edinburgh, is likely to have travelled to the city and may still be there.
Det Supt Neil Hunter said: "We need to speak with Naeem Butt as a matter of urgency. I would urge anybody who knows of his current whereabouts to contact police immediately.
"We believe he may well have travelled to Edinburgh and I would appeal to anybody in that area who thinks they may have seen him in the past 72 hours or so to come forward.
"I would also like to speak with anybody who has had any contact with him whatsoever, either directly or indirectly, since Tuesday.
"Finally, I would appeal to Mr Butt directly to make contact with the police as soon as possible.
"However, I would urge members of the public who may come into contact with Mr Butt to exercise caution and not to approach him directly but to contact the police immediately.
"It is crucial that we speak with him sooner rather than later as he may hold information that is key to this investigation."
He is described as 5ft 10in (1.77m) tall, of medium to slim build with dark hair and brown eyes.
He has a piercing in both ears, as well as a number of tattoos, including a scorpion and peacock on his left arm and a cobra on his left hand.
