A 35-year-old man has been arrested after a suspected acid attack on a girl outside a school in west London.
Teagan McFarlane, 14, remains in hospital with “potentially life-changing” injuries and has undergone surgery.
A 16-year-old boy was also injured outside Westminster Academy, Westbourne Park, on Monday afternoon, while a staff member was hurt trying to help them.
The Metropolitan Police said the man was arrested on suspicion of causing grievous bodily harm, and remains in custody.
The force said “a lone man” threw a substance at the teenagers before fleeing on the Harrow Road.
Det Sup Scott Ware said this was a “horrific attack”.
The victim’s father, Corey McFarlane said that words could not “express the shock, pain, and trauma she is going through right now, both physically and emotionally”.
The police urged anyone with information to come forward.
