Police are investigating after thieves hit a jeweller over the head, twice, with a sledgehammer.
It happened at Davand Jewellers at around 4.30pm on Saturday in Bearwood, in Birmingham.
The jeweller escaped with minor injuries after the four offenders got away with tens of thousands of pounds worth of stock.
The thieves smashed down the front door to the shop and used sledgehammers to break into a glass cabinet in order to gain access to 17 trays of gold.
During the raid, the 52-year-old shop owner pressed a panic alarm, the offenders then struck him twice with the hammer. His wife was also present but was not attacked.
“The victim was lucky to have got away with relatively minor injuries following what was an extremely nasty attack, there was no need for the level of violence used.
“I’m keen to hear from anyone who witnessed any of what happened or anyone who has any information about who may be responsible.”
