A lawmaker in Zimbabwe's ruling party has been arrested after handing himself over to the police investigating the sale of 10000litres of cooking oil on the black market, a weekend report said .
The state-run Herald said police arrested Zanu-PF lawmaker, Zacharia Ziyambi, of Kadoma West, in connection with the sale of the cooking oil consignment.
It added authorities were also keen to question a senator, Chiratidzo Gava.
"Ziyambi is still in police custody and investigations are continuing," police spokesman Oliver Mandipaka said.
"Our specific interest is to critically examine and establish the circumstances surrounding the acquisition of 10000litres of cooking oil from Grafax Cotton," he added.
Ziyambi and Gava are alleged to have signed a letter to acquire the cooking oil from Grafax Cotton purportedly for the benefit of their constituents.
Mandipaka said police impounded the cooking oil as it was being off-loaded in drums from a Nissan truck near a furniture shop.
