Truro acid attack victim in critical condition
A man is in a critical condition in hospital after acid was thrown in his face.
The victim, 29, was attacked at his home in Truro, Cornwall, by an unknown man, police said.
He is now being treated for "life-threatening facial injuries" at the Royal Cornwall Hospital.
Officers want to speak to a man driving a red Peugeot van seen in Carrine Road before the attack at 16:00 GMT on Tuesday.
It is believed the man, who lives in the house with his wife and 18-month-old child, was attacked after he opened the front door.
Police have been searching the area near the house in the quiet residential neighbourhood.
Officers called it a "rare and isolated attack".
Det Insp Sharon Donald, from Truro CID, said: "We are keen to speak to anyone who saw any unusual people or vehicles in the area yesterday, in particular a red van.
"If you are the driver of the red Peugeot van seen in the area, please get in touch with police so we can eliminate you from our enquiries."
Officers have been carrying out house-to-house enquiries, handing out leaflets, and patrolling the area to reassure residents.
