Police have released a new photograph of James Allen who is suspected of killing two people in Whitby. Officers were keen to stress the new image shows Allen with some hair. Previous images have shown him without any hair.
A previous victim of James Allen said he was "lucky" to be alive as he described his shock at seeing the wanted man's face on TV.
Brian Butt, 67, suffered four stab wounds when he was attacked outside his Winchester home in February 2003 by Allen and a accomplice. Allen was jailed for eight years for the attack, the Southern Daily Echo reported.
Mr Butt said: "I saw it on television and I thought I knew the name from somewhere, then I saw his picture and it was definitely him. When I saw it and what he is supposed to have done, I felt sorry for the families of those up there.
"I don't want to talk about what happened. They came here and I was stabbed four times but I was the lucky one. They did take things but I don't want to talk about what happened."
We are investigating a number of sightings in both force areas that have been reported to us, including sightings in the Harehills area of Leeds, and I would repeat our message in urging members of the public if you see James Allen to call 999 immediately.
This operation continues on a 24/7 basis and it will do until we trace and arrest James Allen.
Someone must know where he is. He will have confided in someone and I would appeal to that person to come forward and get in touch with us.
– Detective Chief Superintendent Gordon Lang
Two innocent people have lost their lives and it is absolutely vital that we catch James Allen as soon as possible. If you know where he is now, call us. James, if you are reading this, give yourself up, it is only a matter of time before we find you.

We have had a positive response from members of the public and I would express my thanks for their support.
We are working round the clock to follow up these leads and I would once again reiterate the fact that if you see James Allen, do not approach him but call 999 straight away.
I would urge people to take simple safety measures to keep themselves safe, such as locking their doors and windows.
