A 35-year-old man has been arrested on suspicion of robbery in St Ives.
The man, from Huntingdon, was bailed to Thorpe Wood Police Station at a later date.
The incident, involving a woman in her 20s, took place on October 21 at about 8.30am when she was making a withdrawal at a cash machine in Needingworth Road.
The offender barged into the victim with his shoulder causing her to stumble into the wall before making off with the £10 note in her hand.
Anyone with information is asked to contact the Serious Crime Team at Huntingdon Police Station on 101, or Crimestoppers, anonymously, on 0800 555 111.
