A £5,000 reward has been being offered by police investigating the robbery of a vulnerable pensioner in Pembroke Dock by two men.
Cash was stolen from a safe at the High Street home of the 70-year-old woman six weeks ago.
An armed man, believed to be in possession of a green Ford Fiesta car, is wanted over the crime.
Officers warn Darren John Wilcox, 30, is dangerous and should not be approached by the public.
He is described as white, approximately 5ft 8in tall, of heavy build, with short brown hair and blue eyes.
Mr Wilcox is believed to be from the Cardiff area and to be familiar with Pontypridd and Rhondda.
Dyfed-Powys Police said he is believed to go by aliases of John Gypsy, Darren John, Andrew James Price, Jason Price, Darren Roberts and Damen John Wilcox.
They said he is believed to be possession of a green Fiesta, registration number P796 VBO.
The robbery took place between 1355 and 1400 BST on 13 July when the men entered the house and took money from a safe.
They pushed the woman leaving her "severely shaken and shocked" but uninjured.
The reward will go to anyone offering information leading to the recovery of the stolen money and to the arrest and conviction of the offenders.
Earlier, police advised the public not to approach Wilcox, describing him as "dangerous" and possibly in possession of a firearm.
