The Met Police have confirmed a 37-year-old man, who was detained in connection with the tragedy, has since been let go.
No one else is being sought in connection with the deaths.
The woman has since been named as Yi Chen, 37, and her son as Xing Duan Yuan, aged five, who are both of Chinese origin.
Police were called by the ambulance service at 1.37pm on Tuesday, June 21, to a residential street in Brookside South, Barnet.
Officers, paramedics and the London Air Ambulance rushed to the scene to find Yi Chen and her son both suffering stab wounds.
