BBC Verify has put together a timeline and map of the route taken by the suspect from video and images shared on social media.
We first see the suspect in CCTV footage taken on Highfield Avenue, timestamped at 11:15 BST.
He is jogging along the pavement towards Golders Green Road when he appears to attack a man, who he chases out of view.
According to the Metropolitan Police, officers responded to reports of people being stabbed in Highfield Avenue at 11:16. Police later said two men – aged 76 and 34 – were stabbed on this road, although footage appeared to show the second stabbing was on nearby Golders Green Road.
The next clip, filmed from a car driving north along Golders Green Road, shows the suspect chasing after a man on the pavement.
CCTV footage taken to the north-west on Golders Green Road – timestamped to 11:20 – shows the suspect approaching a bus stop and repeatedly attacking a man waiting there, who he then pushes on to the road and out of view.
In a picture taken about 90m (300ft) further along the road we get the first glimpse of what appears to be a knife being held by the suspect.
Finally, we have verified multiple videos and images of the suspect being detained by police who use two Tasers to force him to the ground and arrest him.
Police can then be seen administering CPR and later footage shows the suspect being lifted on a stretcher into an ambulance.
