Thank you for reading the story.
Police investigating the murder of Eric Tomkinson, which occurred in Crewe on the early evening of Friday 4th January 2013 are appealing for a potential witness to get in touch.
Police are keen to trace the man who was inside the Nisa store on Alton Street at 7.08 p.m. on the night of the incident. So far, all attempts to identify him have been unsuccessful.
The witness is described as white in his mid-teens to early-twenties, of slim build with short, light-coloured hair. He was wearing a green hooded-top, dark jeans and dark footwear.
Major Investigation Team officer, Detective Sergeant Janet Moore said:
“We are keen to trace this young man.
Unbeknownst to him, he may have important information which is relevant to this enquiry.
I would encourage him to come forward and contact the Cheshire Constabulary.
Likewise, if any member of the public knows the identity of this man, I would encourage them to contact the police and pass on his details.
I must stress, the man has done nothing wrong.
He may hold important information.
We need to speak to this man as a potential witness to a murder investigation.’
Paul Ward, 27, also from Crewe has been charged with Eric Tomkinson’s murder.
Anyone with information as to the identity of the man can contact Cheshire police on 101 and quote ‘Operation Tenora’.
Alternatively, information can be given anonymously by contacting Crimestoppers on 0800 555 111.
