MEMPHIS, Tenn. — A Memphis man was arrested Sunday after police say he attempted to set a hospital on fire in Whitehaven, putting nearly sixty people in danger.

Memphis Fire Department responded to a fire at Methodist South in Whitehaven around 3 p.m. on Sunday evening.

An investigation began after MFD declared the cause fire as intentional.

Witnesses told investigators that Devonta Willis got upset inside the emergency department of the hospital and used a lighter to set a mattress on fire.
