A shop keeper chased off a masked man who tried to rob his store.
Police say the offender entered Londis, in Tinker's Drove, between 3.10pm and 4pm on Sunday with a scarf covering his face.
He threatened a member of staff with a knife and demanded cash.
The 56-year-old victim tried to tackle the offender before chasing him out of the store.
The offender was described as white, 25 to 35, stocky, 5'7'' and was wearing a grey hooded top, scarf and a zip-up jacket with an England logo on the back.
Det Con Tony Harlow, investigating, said: 'This was a terrifying experience for the member of staff who showed great bravery to chase the offender out of the shop.'
Anyone with any information should call DC Harlow on 0345 456 4564.
