Alvanley Gardens was taped off by the Metropolitan Police on January 29, after a man in his 20s was found suffering stab wounds to his neck and leg.
He was taken to hospital in a critical condition.
It is unclear at this stage if his condition has changed.
The following day, on January 30, officers arrested a man in his 20s on suspicion of attempted murder.
