A Brooklyn pastor was indicted Thursday on a slew of charges after a deadly fire in 2014 tore through an illegally subdivided building that he owned.

Luckner Lorient, 78, is charged with manslaughter, criminally negligent homicide, and other charges in connection to the Nov. 19, 2014 fire that killed a 24-year-old man and left nine others injured.

Prosecutors said the fire broke out when a water cooler connected to an overloaded electrical outlet burst into flames.

They said Lorient ignored citations to vacate the three-story building in Flatbush.

Instead, he illegally turned two upper floor apartments into single room occupancy housing while operating his church out of a storefront, according to investigators.

They said the subdivided floors were converted to 11 separate rooms and rented to 23 people.

Lorient has pleaded not guilty to the charges.
