Prosecutors in Philadelphia will announce charges Wednesday against a man accused of making explosives inside a home last weekend. 

Firefighters were called to a property on the 7100 block of Montague Street Sunday night for reports of smoke coming from inside a garage.

Two people, a man and a woman, were rescued from the home and treated by first responders at the scene.
