WICHITA, Kan. (AP) — Part of a ceiling has collapsed in a substance abuse recovery center in Wichita, leaving multiple people with minor injuries.

Local media reports say a section of ceiling in the DCCCA’s Women’s Recovery Center collapsed late Wednesday.

Wichita Fire Battalion Chief Tom Carney said a 15-by-30-foot section of the plaster fell into the room below due to water that had accumulated and leaked through the roof. As many as 25 people had gathered in the room below.

The Wichita Eagle reports 12 people had minor injuries.

According to Carney, the dormitories inside the center, which offers services to women struggling with substance addiction, were not affected by the collapse so residents will not have to be relocated.

Maintenance crews will assess the damage Thursday morning.
