A mother-of-three has admitted hurling racial abuse at a pregnant Muslim woman on a bus in Stonebridge after a video of her tirade went viral online.

Simone Joseph, 36, from Willesden Green, branded Hanane Yakoubi and her two friends “Isis bitches”, accused them of having “bombs up their skirts” and shouted at them to “f**** off back to your own country”.

She also threatened to kick Ms Yakoubi, who is 34 weeks pregnant, in the stomach so she would “never have children again” during the incident last Tuesday.

Her outburst was witnessed by shocked passengers on the 206 bus as it travelled in Knatchbull Road, including her own two-year-old daughter who was with her.

Joseph handed herself in to the police three days after a member of the public posted the footage.

Today at Hendon Magistrates’ Court she pleaded guilty to causing racially aggravated distress.

The court heard the row started when Ms Yakoubi boarded the bus at around 10.30am with two other women and a young child in a pushchair.

Prosecutor Darren Watts said: “For no apparent reason the defendant started swearing at her, telling her to f*** off back to her own country.

“The verbal abuse, described as constant swearing, continued for approximately five minutes.

“The bus had a number of other passengers present, including children and indeed the defendant’s own two-year-old child.

“Other individuals appeared shocked and distressed by the footage.”

The driver stopped the bus to try to stop Joseph but she carried on, the court was told.

She was also seen walking up and down the bus filming her victim.

“At one point she said she would kick the complainant in the stomach and she would never have children again,” Mr Watts said.

“The complainant is 34 weeks pregnant.”

Tony Meisels, representing Joseph, said: “She apologises for the hurt and distress caused to the persons on the receiving end of her behaviour.

“She recognises this was totally unacceptable and it was totally out of character.

“She is appalled, shocked and disgusted by what happened on that day.

“She wants to convey her regret to the victims.”

Joseph was released on unconditional bail and will be sentenced on November 13 at Hendon Magistrates Court.
