(KAIR)--A 53-year-old man is in custody in connection with Tuesday's home explosion in north St. Joseph.

KQ2-TV, citing Saint Joseph Police, reports no formal charges have been filed and the investigation is ongoing. 

Police received several reports of an explosion at a home in the 1200 block of Prospect Avenue around 9:30 Tuesday morning.  

When emergency crews arrived on the scene, they found that the home was no longer standing, reduced to rubble in the explosion. 

Neighbors were able to help three people to safety.

The three, who were inside the home at the time of the explosion, were transported to Mosaic Life Care with what police call non-life threatening injuries. 

The ATF is investigating the incident, with the possibility of illegal fireworks a focus of the investigation.
