The Metropolitan Police believe Ezedi is dead after CCTV showed him leaning over railings at Chelsea Bridge on the night of the attack.
He was last seen on camera just before 11.30pm when as he crossed over the bridge and entered nearby Battersea Park, before then crossing back over the same bridge minutes later.
The relationship between Ezedi and his ex-partner breaking down is being considered as a possible motive for the attack.
On Friday, Commander Jon Savell admitted thatEzedi’s body may never be found due to the speed of the current in the River Thames.
