A child is fighting for life in hospital after being bitten by a dog in Kent.
The child was rushed to a London hospital following the incident in the Jenkins Dale area of Chatham on Tuesday evening.
Police said that two people have been arrested in connection to the incident, while the dog was shot dead to ensure the safety of the public.
The force appealed to members of the public who may have footage of the incident to contact police and not to share it on social media.
Neighbours said they heard a shot fired and saw a child covered with a blanket being carried to an ambulance.
Jaspreet Uppal said: "First I heard a gunshot, there was a dog on the floor. A few officers carried out a child from the back area of the flats. There is a little park there. I could not see the child, they were covered. I think they were quite small."
Tracey Crouch, MP for Chatham and Aylesford, said on Twitter: "Horrible news from Chatham this evening. My thoughts and prayers are with the child and their family tonight."
A Kent police spokesman said: “Kent Police was called at 5.26pm on Tuesday 4 April 2017 to an incident where a child had been bitten by a dog, sustaining life threatening injuries, in the Jenkins Dale area of Chatham.
