A 35-year-old man has been arrested on suspicion of causing grievous bodily harm after what is believed to have been an acid attack outside a school in west London earlier this week.
Detectives said a 14-year-old girl has been left with potentially life-changing injuries after the incident at Westminster academy on Monday afternoon, while a 16-year-old boy and a teacher were hospitalised then discharged, having suffered less severe injuries.
