After inspecting the fire-ravaged FR Tower on Friday, the minister told the media, "I believe that the incident was down to negligence. This wasn't an accident, it's murder."
"We will take legal action (against building owners). No matter who the owner is, whatever his influence, circle, power or last name - no one will be spared. Unlike the past, tough measures will be taken."
Four floors of the 23-storey building on Kamal Ataturk Avenue, a commercial district of the upscale neighbourhood, suffered extensive damaged in the fire that started sometime after 12pm on Thursday.
