A father and son were seriously injured in a double stabbing in north London which police said "could easily have been fatal".
A 65-year-old man, who recently arrived in Britain to celebrate Christmas with his family, was attacked with his 37-year-old son at about 7.50pm on Christmas Eve in Finsbury Park.
The men were seriously hurt and needed hospital treatment but have since been discharged.
They were both in a grey panel van when they became involved in an altercation with the driver and passenger of a black Smart car in Green Lanes, near Manor House Tube station.
Scotland Yard said the driver and passenger were both black males.
The row progressed into Hermitage Road before it ended up in Vale Grove.
On Friday, detectives released two photographs of men they would like to speak to in connection with the stabbing.
One man has been named as Kyroe Oscar Howsen, 24, from Haringey.
A CCTV image of another man wanted by police has also been released.
Scotland Yard has asked anyone with information on the whereabouts of either men to contact them.
Detective Constable Leon Ure, from the CID on Haringey borough, said: "This was a very violent attack and the injuries were serious and could easily have been fatal.
“The elder victim had just arrived in the county to spend Christmas with his family; instead he and his son had to be rushed to hospital.
“We urgently want to find the persons responsible and I would urge the public to contact police if they have any information."
Anyone with information is asked to contact police on 101, or contact Crimestoppers, anonymously, on 0800 555 111 or at crimestoppers-uk.org.
