Most of the arrests were made at the Roadport bus station in central Harare where buses from the region arrive and depart, a police spokesperson told the paper.
"We have been conducting raids on a daily basis on the spots that are prominent in foreign currency deals like Roadport and we have undercover officers that are stationed at these areas," said Loveless Rupere.
"We can confirm that to date 134 arrests have been made," he said.
The black market in scarce foreign currency is reported to be thriving in Zimbabwe, where one US dollar changes hands on the streets for up to four times its official value.
Zimbabwean police recently launched a new blitz to enforce a ban on street vendors, touts and black marketeers in the city centre.
The clean-up, dubbed Operation No Going Back, is a follow-up to Operation Restore Order, launched five months ago that also saw the demolition of houses, cottages and backyard shacks across the country and the arrest of tens of thousands of traders.
The operation was roundly condemned by the UN. - Sapa-dpa
