A woman and two men arrested in connection with a violent betting shop robbery in Norwich remain under investigation.
Two masked men stormed into the Tony Clayton betting shop in George Hill, Old Catton, near Norwich, and attacked a man who suffered a broken eye socket and dislocated shoulder after he was beaten to the ground before the men grabbed a large quantity of cash and fled in a Ford Ka.
The car was parked at the Woodman pub car park opposite the shop, where a female driver had been waiting for them.
Police launched an appeal for witnesses following the robbery, which happened at about 7.30pm on Tuesday, May 28.
Three people - a 21-year-old woman and two men, aged 26 and 28 - have since been arrested.
All three were questioned by police and have since been released under investigation.
A police spokesman said enquiries are ongoing.
