Police are investigating a suspected hate crime after a man allegedly tried to pull a Muslim woman's hijab off on a Tube platform.
Tweeting under the name Aniso Abdulkadir, she posted a picture of the man who allegedly attacked her, writing: "This man at Baker Street station forcefully attempted to pull my hijab off and when I instinctively grabbed ahold of my scarf he hit me."
She continued: "He proceeded to verbally abuse my friends and I, pinning one of them against the wall and spitting in her face."
Ms Abdulkadir added a woman who was present was also threatening and verbally abusive.
She urged others to share the image in order to identify the suspect, earning more than 24,000 retweets by Sunday afternoon.
A British Transport Police spokesman said the incident is being investigated as a hate crime, adding: "Behaviour like this is totally unacceptable and will not be tolerated.
"This incident has been reported to us and we're investigating."
However, the alleged suspect tweeted to protest his innocence, saying the accusations were "completely false". Pawel Uczciwek claimed he had been defending his partner from a racist attack, and trying to diffuse a "racist attack from three other random females".
He wrote: "I would like to confirm I never hit or attacked anyone I simply defused the situation by separating them.
"The police is fully cooperating with me and will be able to obtain CCTV footage showing the three women attempting to attack my partner because we are in an interracial relationship."
Mayor of London Sadiq Khan said in June there had been a spike in the number of racist incidents recorded since the London Bridge attack.
The latest stats showed a rise in Islamophobic incidents with 54 racist offences recorded on Monday, June 5 up from the previous daily average of 38.
