The Metropolitan Police said in a statement that officers and a 61-year-old man were called to an address on Noel Park Road in Wood Green around 7.20pm on Friday night following concerns for the welfare of residents.
While the three were in a communal area, a man approached them before assaulting them, the Met said.
The 61-year-old man suffered stab injuries, with a report on his condition still pending.

Police said a crime scene remains in place, and at the this stage the incident was not thought to be terrorism-related.
