DENVER — Ten people were taken to hospitals and dozens were displaced after an explosion and transformer fire at a Denver assisted living facility, officials said.

Firefighters responded at the Eastern Star Masonic Retirement Campus and controlled the blaze Wednesday, according to a Denver Fire Department statement.

The injuries may have been minor but more detailed information about those hurt was not yet available Thursday, department spokesperson Capt. Luis Cedillo said.

Another 87 people were displaced. The facility was boarded up and they would not be going back soon, Cedillo said.

“If they do go back, it will be only to pick up personal items in their apartments,” Cedillo said.

Residents would be able to do so only in apartments deemed safe, Cedillo added.

A preliminary investigation indicates a power line was accidentally struck during construction work, causing the explosion, the department said.
