Detective Superintendent Alexander Castle said: "Officers are on scene following this horrific incident. Three victims - a woman and her two young children - have been taken to hospital for treatment.

"Three other people - all adults - have been taken to hospital for injuries sustained, we believe, as they came to their aid. We will update as soon as we know more about their conditions.

"Three police officers have also been taken to hospital after they responded to the incident. Thankfully we believe their injuries to be minor. While tests are ongoing to determine what the substance is, at this stage we believe it to be a corrosive substance.

"A man was seen fleeing the scene. We are drawing on resources from across the Met to apprehend this individual and work is ongoing to determine what has led to this awful incident."
