Witnesses have described a “horrific” scene after a mother and her two girls were doused in their car with a “corrosive substance” in south London.

The Metropolitan Police said emergency services were called to Lessar Avenue, near Clapham Common, at 19:25 GMT after reports of an attack with a suspected “corrosive substance”.

A couple who live on Lessar Avenue said they ran into the street after hearing a cry for help and then the sound of a car crashing.

Labour London Assembly Member Marina Ahmad said there had been a traffic collision on Lessar Avenue “with a man assaulting occupants in a car”.

"Crews also used specialist equipment to detect a corrosive substance that is believed to have been used in the incident.

A joint statement by local Clapham Common councillors Alison Inglis-Jones and Ben Curtis said they and the wider community are “in total disbelief and shock” at what had happened.
