A shop worker in his early 80s was hospitalised after being assaulted in a violent robbery in Newport on Saturday 9th September.
Two men pretended to be customers before distracting and assaulting the staff member, leaving his with a cut to the eye.
The offenders went on to cause damage to a display case and made off with approximately £7,000 worth of jewellery.
Police are appearing for information.
One of the offenders is described as white and in his late teens or early twenties whilst the second is said to be mixed race and around the same age.
