'Armed' robber ties up postmaster in Treharris PO
Police are hunting a robber who tied up a postmaster before escaping in the man's car with cash from the till.
The intruder hit the postmaster over the head after forcing his way to the post office in Treharris, near Merthyr Tydfil, as it was closing on Thursday.
He threatened the man with what he claimed was a gun.
The attacker was described as about 6ft 4in (1.93m), with dark eyes, and was wearing a black zip-up jacket with white writing to the left side.
South Wales Police said he was wearing a black woolly hat and what might have been a scarf that covered most of his face. He was also carrying a large black sports holdall.
The incident happened between 1715 GMT and 1800 GMT at the post office on Fox Street.
After taking what police described as a "large quantity" of cash, the attacker tied up the postmaster and took the keys to his black BMW registration M17 VJL, which was parked in the car park of the nearby Navigation Hotel.
Det Con Kevin Barry, from Merthyr CID, said: "This was a nasty incident which we are taking very seriously.
"The victim was hit to the head during the incident and sustained a minor injury for which he required hospital treatment, and has been left extremely shaken by what happened.
"An incident like this is very rare for the area, and we are keen to speak to anybody who may have information about who is responsible, or who may have noticed something suspicious."
Anyone who has any information is urged to contact Merthyr CID via 101, or contact the independent charity Crimestoppers on 0800 555 111.
