Police have warned the public not to approach a man being hunted over a chemical attack on a woman and two girls in south London.
The suspect, named as Abdul Shokoor Ezedi, from Newcastle, has significant injuries to the right side of his face, according to police.
Ezedi, believed to be aged around 35 years old, was last seen on Caledonian Road in north London earlier today, officers said.
He is believed to have travelled down from Newcastle on the day of the attack and could be heading back, according to police.
Both Northumbria Police and the British Transport Police are helping the Metropolitan Police with the manhunt.
Police have also confirmed that a car involved in the attack belonged to Ezedi, while the substance used in the attack was alkaline.

The attack took place near Clapham Common last night.
A 31-year-old mother and her three-year-old daughter, alongside her other daughter, aged eight, remain in hospital following the attack.
The mother and the younger child may have suffered life-changing injuries, according to police.
Officers say Ezedi attempted to make off from the scene in a car following the incident, but collided with another vehicle, and then made off on foot in the direction of Clapham Common.
Police said the suspect was known to the woman and described the attack as "targeted".
Superintendent Gabriel Cameron, of the Metropolitan Police, said: "If you see him [Ezedi], I plea do not approach him.
"And if you see him, call 999.
"He has significant injuries to the right side of his face."
Asked if he would be caught, he added: "We have got a significant asset looking for this man.
"We will catch him. I am wholeheartedly confident."
