A MAN armed with a knife demanded money from staff at Headington Post Office just after midday today. 

Police were called to the London Road premises following reports of an attempted armed robbery.

A spokesman said staff refused to hand over any money to the man armed with a knife. 

A Post Office spokeswoman confirmed the incident had taken place and said: "Any robbery or attempted robbery is very traumatic for the victims and we will be supporting the police in their efforts to apprehend those responsible. 

"We would urge anyone with information to come forward and contact the Police or call Crimestoppers anonymously on 0800 555 111 as soon as possible."
