At least 18 pupils and one teacher were killed when the roof of a private school collapsed in Dir Colony, Peshawar, on Thursday, according to the BBC. The school is known as Khair Education System.
The Capital City Police Officer (CCPO) in Peshawar confirmed that the owner of the school has been arrested, the BBC reports. In a released statement, the CCPO said the school operated as an educational trust.
Preliminary investigations indicate the building was structurally weak, which caused it to give way, according to the BBC. The BBC did not report the total number of people injured or the ages of the pupils in the material available.
The collapse has drawn attention to the condition of private school buildings in the region. The CCPO's statement that the structure was already weak points to long-standing maintenance issues rather than a sudden external cause, though the BBC notes the investigation is at a preliminary stage.
Pakistan has seen repeated incidents in which school buildings have failed, and the arrest of the owner signals that authorities are treating the case as a matter of accountability as well as rescue.
What to watch next: whether investigators release further findings on the building's condition and whether additional arrests or charges follow.
