Police are appealing for witnesses after two betting shops were robbed in Colchester.
The first incident happened at around 7.45pm on October 26 at Corals in The Willows. A man wearing a red mask and carrying a hammer smashed the window of the premises and demanded cash. He left in the direction of The Thomas Lord Audley School with an amount of money.
He wore a black jacket and a red hooded jumper with the hood up.
A masked man later entered Ladbrokes in Prettygate at around 9.15pm, went behind the counter and grabbed a three-figure sum of cash.
He was described as white and around 5ft 9ins tall. He wore a red mask, grey jogging bottoms, a grey hooded top and dark trainers.
Police are linking the two robberies and officers remain at both scenes making enquiries.
Anyone with information is asked to contact Dc Duncan Collyer at Colchester CID on 101 or Crimestoppers, anonymously, on 0800 555 111.
