Police are hunting a man after a double stabbing which left a father and son seriously injured.
A 65-year-old man and his 37-year-old son were stabbed repeatedly in an attack in Finsbury Park on Christmas Eve.
The incident happened after an altercation between the driver and passenger of a black Smart car and the father and son who were in a van.
