The original E-fit features a man with dark hair andÂ a ginger beard, which social media users mocked online for appearing unrealistic.
Now the force has admitted that the E-fit could be improved and work is underway to create a new version.

Officers want to trace a man who used a knife to threaten a shopkeeper during an attempted robbery in Royston.
He struck at an off licence on Station Road at 8.40pm on Friday, September 21 but left empty-handed.
The crook spoke with a local accent and was around 5ft 4ins tall.
South Yorkshire Police said that although the force can '˜see the humour' in the original E-fit, it was issued in relation to a serious incident and a new one will be created.Â
The force said it can '˜come up with a better interpretation of the offender's description'.
Anyone with information should call South Yorkshire Police on 101.
