ROBBERS escaped with cash after tying a night porter to a tree at Fleet motorway services on Wednesday last week.
Armed with a pistol and a small knife, the two thugs struck at 1.45am at the Days Inn off the southbound carriageway of the M3.
They rang the buzzer at the entrance door, and the 21-year-old porter let them in believing they were late arriving guests.
As the pair entered the reception area, they overpowered the terrified porter and tied him up.
After rifling the reception till and safe, the two men bundled him outside and bound` him to a tree, after rifling the reception till and safe.
The porter managed to struggle free and alerted his manager who raised the alarm.
Police said the victim was not injured, but was left shaking and extremely distressed by his ordeal.
Officers believe it is almost certain that the robbers escaped by car.
They have questioned guests at the hotel, but have so far failed to find any witnesses.
Detective Sergeant Alan Hastings, of Aldershot CID, said: "Days Inn is right next door to the main service station, and even at this time of night there would have been plenty of cars in the car park.
"We are very keen to speak to anyone who was at the services and saw anybody acting suspiciously or a car driving away at speed."
One of the raiders was white, in his early 20s, 5ft 7in tall, medium build, with short brown hair.
He was wearing a black jacket and dark coloured trousers.
His slightly shorter accomplice was black and wearing a dark hooded top which covered his face.
Anyone with information is urged to call Aldershot CID on 0845 045 45 45, or the anonymous and free Crimestoppers line on 0800 555 111.
