Two men are nursing critical injuries after they were wounded by the debris of a building that was being demolished within Nyamira Town.

The two were doing a renovation to mend a wall that was partly demolished by county engineers who were making a road reserve at around Water Supply area behind County Commissioner's offices.

Some of the workers who were undertaking the construction but were not injured said the two were hit by debris and stones from the third floor of the storey house and they passed out.

The two were rushed to hospital by the owner of the construction only identified as Auka.

According to Nyamira County Commissioner Amos Mariba, the building was not approved for the renovation and that the works were being undertaken illegally.

The County Commissioner led a team of security agencies to ascertain the state of the building.

"We have confirmed that the house was condemned because it was standing on a road reserve and part of it had been knocked down from the reserved land," Mariba said.

The Commissioner said the owner of the building will be prosecuted for contravention rules of physical constructions and development.

The owner failed to seek approval and the works that were being done were illegal.

"The owner will have to face the law so as to serve as a lesson to other investors," he said.
