A man had a knife held to his throat by an armed robber as he walked near a care home in Leominster.
The man was approached from behind by the thief, near to the BUPA Care House at 2350 BST on 18 September.
He was threatened before handing over his wallet.
The offender fled from the scene towards the Spar car park.
He is in his late 20s, with collar length, brown, wavy hair and baggy clothing.
Police say they want to speak to the drivers of two lorries that stopped at traffic lights at the bottom of Bargates in the early hours of 19 September, or anyone with any information.
