A thug attacked a young mum in front of her teenage son during a raid in County Durham.
The 32-year-old woman and her 12-year-old son were at home in Pankhurst Place, Stanley, last Monday at around 10.30pm, when she was hit in the head and had a liquid sprayed in her face.
She was taken to the University Hospital of North Durham for treatment.
Police investigating the attack have now released an artist impression of the man.
Det Con Dean Haythornthwaite, from Stanley CID said: "Our enquiries at this stage suggest this was not a random attack, but we are keeping an open mind as to the motive. Fortunately the victim was not badly hurt, but this was still a very serious incident in what is normally a quiet street."
The woman saw a stranger on the porch and he shouted out a confusing explanation of who he was and why he was there, which left the woman very suspicious and she decided not to open the door to him.
But her son answered the door and as he opened it the man barged his way into the house, knocking him to one side.
The attacker is described as 5'8" tall, with a tanned complexion, thick eyebrowns and was of thin build. He was wearing a 'Superdry' jacket with a red logo on the front.
Anyone who recognises the man from the e-fit image is asked to contact police on 101 or they can call the independent charity Crimestoppers on 0800 555111.
