CCTV released over Christian Bagley stab death
Police have released new CCTV images of men they want to trace as they continue to hunt for the killer of a man stabbed on Father's Day a year ago.
Christian Bagley, 30, was stabbed twice as he walked under the Hunderton Bridge in Hereford on 21 June, 2015.
The images, released 18 months after the stabbing, show two men police want to speak to.
Police have said four people arrested in connection with his death will face no further action.
Mr Bagley was killed as he returned from seeing his young daughter.
Police say the men they want to speak to were both in the area the same weekend Mr Bagley was killed and have not yet been identified.
Det Ch Insp Leighton Harding said they have not been identified as suspects, but police are keen to speak to them as they could hold key information which could be vital to the investigation.
One man was seen entering Costcutter on Saturday 20 June 2015.
Another man was seen walking along Villa Street in the direction of the Hunderton Bridge at about 22:20 BST on the evening Mr Bagley was killed.
Det Ch Insp Leighton Harding said: "I would like to appeal directly to those who know who is responsible and I want them to think about the fact that there is a little girl who is now facing her second Christmas without her father."
