A thug repeatedly stamped on a woman’s head during a robbery for just £20 as witnesses stood by filming the attack on their phones.
The 45-year-old victim, who police described as vulnerable, was left with a fractured skull after the horrific attack in the early afternoon.
Her arm was broken in several places and she was left lying injured on the pavement in Brixton, south London.
A number of witnesses filmed the assault and subsequently shared it on social media, police said.
The woman is still recovering from her injuries after the attack in Ramilles Close on December 15.
Scotland Yard has now released a CCTV image of the suspect, who was described as “a danger to the public”.
Detective Constable Nicky Dixon, from Lambeth CID, said: "This was a brutal attack of a vulnerable woman in broad daylight. She was unable to defend herself and was left semi-conscious on the ground with serious injuries which required emergency treatment.
"We know the assault was witnessed by people who have not come forward and I would urge them to speak with us.
"This is man is a danger to the public and needs to be caught - someone knows who he is and I appeal to you directly for your help."
Police described the suspect as a light-skinned black man, with a dark hooded top, a bottle green gilet and dark tracksuit trousers.
