The victim was left shocked and distressed after being subjected to the vile assault in the capital just after 8am on October 4.
She was walking alone along the busy shopping strip when she was approached by a man who repeatedly told her to remove her headwear.
When the woman refused the thug became more aggressive and grabbed the woman’s headscarf, attempting to remove it.
He succeeded in unpinning the scarf but failed to remove it when the woman managed to get away.
The man fled in the direction of Marble Arch.
Detectives said the victim was not injured in the attack, which cops are treating as an Islamaphobic hate crime.
The suspect is described as a white man, aged between 30 and 40, with short black greased hair.
He is around 5ft 5ins tall, of medium build and he was wearing a grey sweatshirt with light blue jeans.
Det Sgt Steve Stamp said: “This was an unprovoked and hate filled attack in broad daylight in the middle of a busy street.
“The woman was targeted by this suspect purely based on what she was wearing.
“Racially and religiously motivated crimes will not be tolerated I would appeal to anyone who witnessed this attack to contact police. “
