Central Province Police chief Standwell Lungu said the incident happened around 17:00 hours at the business premises situated in the town centre.
The attack comes barely a week after four armed men staged a daylight robbery in which they got away with K100, 000 cash.
The masked men armed with two shotguns and an axe stole the money from a local business executive from Big Bite Bus Station as he was taking it to a local bank.
The attackers, who were driving an unregistered Toyota Sprinter, blocked the business executive’s car in front and ordered the occupants to lie on the ground and surrender the money.
The driver of the Caravan, registration number ACP 7477, who resisted orders to surrender the money, was viciously attacked by one of the gunmen who hit him on his mouth with a shotgun butt. He sustained broken teeth and cuts on his lips.
In yesterday’s case, Mr Lungu said the three men snatched the money from a cashier and later locked her inside the office before they vanished from the premises.
He said Police had launched investigations into the matter.
He also said Police were still investigating the incident in Serenje last week where a Zambia Wildlife Authority (ZAWA) officer was shot dead while others had their money stolen.
Mr Lungu said the Central Province Police command had beefed up security in the district.
In the early hours of last Saturday, a man armed with a shotgun attacked a guest house in Serenje and killed a ZAWA officer, Webster Chitambala, 44, and got away with K5, 059 which he stole from other guests.
The province has in the recent past recorded a number of robberies and killings, particularly in Mkushi, Chisamba, Kabwe and Serenje.
