Police spokesman Inspector Tafanana Dzirutwe said police had picked the four suspects in connection with the robbery case.
“We have picked up four employees of the bank and they are assisting with investigations. Some of the cash has actually been recovered but I cannot give further details as this would jeopardize police investigations,” said Dzirutwe.
The four reportedly stage managed a robbery Saturday night when some suspects approached the manager of the bank at his house.
One suspect, who was armed with what looked like a pistol, allegedly demanded safe keys from the supervisor who told him the keys were with another employee.
The manager reportedly drove to the vehicle to where the teller was staying before going to the bank were the suspect opened the safe and took the money.
After the suspected robbery, the manager was allegedly ordered to drive the suspect to Gwanda but the vehicle was later found abandoned outside Gwanda town.
The manager purported to have been dumped along the way, Inspector Dzirutwe said.
“We strongly suspect that this was an inside job given the circumstances under which the alleged robbery was committed,” he said.
The firearm used in the alleged robbery was recovered in a bushy area along Mtshabezi river were the suspects had dumped it.
Sources said more than $100 000 had so far been recovered following the arrest of the bank employees.
Since Zimbabwe dollarized its economy in 2009, the country has witnessed a series of thefts by bank employees who continue to clamour for a pay hike.
