Detectives hunting a gang who left a vulnerable woman fighting for her life have released CCTV footage of them firing fireworks at a house from their moving car.
The gang are believed to have targeted a number of homes in the Barking area of east London during the night of Friday, November 13.
One of their targets was a residential care home in Beccles Drive where a fire caused by the gang left Donna Stringer, 43, who has learning difficulties and needs a wheelchair, in a critical condition.
Seven other residents from the property had to be found alternative accommodation due to the damage caused by the fire.
Detective Sergeant Karl Dines, from Barking and Dagenham CID, said: "As you will see in the footage that we have released today, this was a deliberate act where fireworks were thrown at a number of homes.
"This is a deeply upsetting incident involving an innocent and helpless victim who has severe learning difficulties.
"Donna is fighting for her life in hospital; medical staff are working tirelessly around the clock to keep her condition stable in the hope that she will recover.
"The fire has caused significant damage to the care home and devastated Donna's loving family.
"It is vital that anyone who has any information about this incident comes forward and shares what they know as soon as possible.
"I would like to hear from anyone who has any information that may help us identify who is responsible."
A photograph showing critically injured Ms Stringer on life support in hospital was also released by police along with the CCTV.
Council leader Darren Rodwell said: "This was an extremely cowardly act on some of the most vulnerable people in our community. It was not just an attack on them but an attack on our whole community."
