A refugee who was told he "didn't belong in this country" said his son's sense of British identity has been left shaken after witnessing the abuse.
Rohullah Yakobi said he felt "immense pain" when his British-born son Sa-aadat, 10, burst into tears after overhearing the incident last Thursday.
Mr Yakobi, tweeted what happened when he went to speak to neighbours and has been overwhelmed by the response he has received.
