Benjamin Katabana stabbed Uchenna Okirie, 33, to death in the corridor of Somerleyton House, in Norwich's Golden Triangle, after luring him out of his flat through a series of goading WhatsApp messages.

The 28-year-old had denied murder but offered a guilty plea to manslaughter with diminished responsibility.

But following a trial at Norwich Crown Court, a jury took less than six hours to find him guilty of murder.

The killing was captured on CCTV in the accommodation block, with the footage showing Katabana stab his victim once before going on to repeatedly attack him and kick him in the head - a violent loss of control his defence said was due to his traumatic upbringing in the DRC, where both his parents and a sister died.
