Five people were killed at Boterekwa in Shurugwi when a lorry on its way to Tongogara Grain Marketing Board developed a break failure and the driver lost control of it.
The incident happened on Thursday last week.
Midlands Police spokesperson Ethel Mukwende was not reachable for comment.
An eye witness who refused to be named said that the truck belonging to a man identified as Zhou lost its brakes while descending the steep and sharp curves at Boterekwa.
"The truck was carrying bags of maize and some boys were sitting on top of the bags at the back. The lorry had break failure while descending the slope and the driver could not negotiate the curves and this saw the truck overturning and killing five people," said the eye witness.
Botorekwa is a black spot where tens of people have been killed in accidents over the years. The locals refer to the spot as 'the butcher'.
The black spot has also claimed more than 10 lives in a space of three months. In another incident a haulage truck lost its brakes and hit an oncoming Toyota Noah killing its 4 passengers who were from Dombojena.
Traffic Safety Council national spokesperson Tatenda Chinoda said that the design at Boterekwa was the best engineers could do on a mountain road and the burden is on drivers to ensure safety.
