In a new update, the force revealed that Ezedi, 35, was last seen at King’s Cross Underground Station at 9 pm on Wednesday.
Commander Jon Savell said: “Following the attack, we know he travelled from Clapham South Underground Station to King’s Cross Underground Station., I want to appeal to anyone who may have seen him travelling on this route between 7.30 pm and 8 pm.
“The latest confirmed sighting of the suspect is at exactly 9 pm when he is seen boarding an underground tube at Kings Cross station on the Victoria line southbound.”
The police have urged him to “do the right thing and hand yourself in”, as it emerged officers have found “significant and important” evidence during searches.
Ezedi, from the Newcastle area, who is described as having very “significant injuries to the right side of his face”, is still on the run following Wednesday’s attack in Clapham, south London.
A 31-year-old mother, believed to be known to Ezedi, was attacked with a corrosive alkaline substance and remains “very poorly” and sedated in hospital, with her injuries thought to be “life-changing”.
The injuries to her daughters, aged three and eight, are “not likely to be life-changing”.
