Officials believe they now know what caused that July 8th fire in the East Village.
Investigators say the blaze at 240 east Houston Street was caused by unapproved wires strung across several residential decks on the building's roof.
The four-alarm fire on Houston Street was caused by the use of unapproved electrical wiring. Fire marshals said the roof of the building was converted into private decks for the residents.
Some residents had stretched electric cables to the roof from their apartments so to use lighting and appliances. Wiring also was stretched underneath roofing materials.
Twenty-eight firefighters and civilians were injured in the fire.
