A 50-year-old man was tied up and threatened with a knife during an armed robbery in Lane End restaurant on Thursday.

A pair of men entered The Lane End Tandoori – formerly The Osborne Arms – in High Street at around 9pm on December 29.

The robbers discovered the victim – who was alone in the restaurant at the time – and stole his wallet containing cash, a driving licence and bank cards.

They also demanded the pin numbers to his bank accounts.

The robbers are described as Asian men in their mid to late thirties, around six foot with short black hair and wearing jeans.

One was wearing a black coat and the other a red jacket.

Investigating officer DC Tim Robins, from High Wycombe Force CID, said "Thankfully the victim was not injured but was understandably shaken by the incidents.

"I would like to speak to anyone who noticed any suspicious activity at around the time of the robbery.”

Anyone with any information is asked to contact Thames Valley Police on 101 or Crimestoppers anonymously on 0800 555 111.
