A textile dyeing factory collapsed in Egypt, killing six people and injuring 22 in an accident blamed on poor construction, authorities said Monday, The Dailystar reported.
A "design defect" caused the disaster near the capital Cairo Sunday, according to Gamal Al-Taruti, head of the Interior Ministry's public safety department.
"The building did not meet construction standards," he told.
An initial investigation found that the accident was caused by the unauthorized construction of a third floor at the factory, a judicial source said on condition of anonymity.
An entrepreneur involved in the construction was detained, while arrest warrants were issued for two others as well as the owners of the building, the source said.
Such accidents are common in Egypt where many buildings are old and violations of construction laws are frequent.
