A gang of armed robbers on Monday morning pounced on an Engen Service Station in Murombedzi where they abducted three guards and a motorist before taking off with a strong box with cash amounting to US$16 500.

Police say the robbers, numbering six, descended on the service station around 3 am Monday morning wielding pistols.

The armed robbers then purported to be police officers and accused the guards of being part of a racket of cattle rustlers, before forcing two of the guards into one of the  robbers get-away cars.

It is alleged the guards were then driven for some three kilometres from the service station towards Kutama, where they were tied up before the burglars went back to the filling station, and once again abducted two more people, a guard and a motorist, and tied them at the same spot as the first two victims.

Later, the robbers broke into one of the service station offices where they took away a safe weighing 200 kgs and loaded it into one of the two cars they were using.

The safe had US$16 500 cash.

Police say one of the get-away cars was an unregistered white BMW while the other was a Toyota Raum.

No arrests have so far been made in connection with the robbery.
