Police have called for witnesses following an attempted raid on a Thomas Cook branch in Camberley in Surrey.
A female member of staff was threatened before she was able to open the store door and shout for help before the offender left empty handed.
The incident took place on Friday lunchtime at the Thomas Cook store on the town’s High Street.
A man in his late 40s from the London area was arrested a short time later at Camberley railway station on suspicion of attempted robbery.
Police said they want to speak to two youngsters who it is believed could have recorded the attempted robbery on a smartphone.
Investigating officer Detective Sergeant Sherren Smith from Guildford CID, told local news website Camberley People: “I would appeal to anyone who was in the area around the time the incident took place and who has information to contact officers.
“I would particularly like to speak with two youngsters who were seen looking in the window of Thomas Cook as it is believed they may have recorded the incident on a mobile phone and this could prove to be vital evidence.”
