An 18-year-old girl turns around as she withdraws cash from an ATM - and is faced with a knife-wielding robber.
The terrified teenager was robbed at knife point in a bank in the quiet Devon market town of South Molton on Friday evening.
Devon and Cornwall Police have released dramatic CCTV footage of the incident which lasts just 90 seconds and occurred at Lloyds Bank on East Street just before 9pm.
Police said the victim was standing in the foyer of the bank about to withdraw cash from the machine when an unknown man approached her.
"He was holding a knife and demanded that she withdrew £100. She complied with his demands and drew out the cash and gave it to him," a force spokesman said.
"He asked her to wait in the foyer for two minutes before leaving and he then made off."
The robber is described as white, in his early 20s, 6ft tall, of scrawny build with dark brown hair, dark eyes and dark eyebrows. He was wearing a black raincoat with the hood up.
The coat has a distinctive thin white strip which runs horizontally across the top of the shoulders. He was also wearing a black scarf that covered his nose and mouth, with a thin red line horizontally across it.
The knife was described as a black plastic-handled kitchen knife with a 6in blade, which was serrated all the way down with a straight flat back.
Detective Constable Daryl Marvelly, who is leading the investigation, said: "Although the victim was unharmed, she was clearly shaken up by this distressing incident.
"We would like to speak to anyone who may know the man shown in the images or may have witnessed the incident."
