A TEN-year-old is among three people doused with acid after a “stranger” reportedly knocked on their front door.
Emergency crews were scrambled to the flats in Colindale, North London, at around 7.20pm yesterday.
They found the child, a woman, 36, and a 46-year-old man injured after a corrosive substance was thrown at them.
The victims were taken to hospital with non-life threatening injuries and have since been discharged, police confirmed.
Horrified neighbours said the child and two adults were attacked when a “stranger” knocked on their door and chucked the substance.
One said: “I saw a little girl come out in PJs, no shoes, with a lady.
“Both were taken in an ambulance. I’m sure it was an acid attack as police were running in with water bottles.”
Someone else added: “Apparently a stranger knocked on their door, they opened and were attacked.”
Dramatic pictures show a large black mark burned into the floor outside the flat with streaks of liquid still visible on the door frame.
Police confirmed no arrests have been made yet with officers still investigating.
They said some cops were treated at the scene after entering the address but none of their conditions are thought to be serious.
The Met added: “An investigation is underway following an incident in Colindale where a corrosive substance was thrown.
