Updated with police statement.
Somebody playing with some chemicals in a Readville apartment this morning caused an explosion that blew his hands off, gave him extensive second and third-degree burns and injured at least four other people.
The Herald reports police now think the newly handless man may have been trying to make fireworks.
A second person was also taken to a local hospital with serious injuries. Police say three other people were treated at the scene.
EMTs went into triage mode to handle all the people coming out of the building. Police and firefighters went through the building and a neighboring one to evacuate residents. The police bomb squad and the BFD arson squad responded.
Firefighters reported heavy smoke from the basement before they knocked the fire down.
Police recovered a quantity of a potentially explosive chemical.
Ed. note: Police at the scene referred to potassium chloride, but see the comments for why it might have been potassium chlorate.
