Man held over 'racist' attack on boy
A man has been arrested over an attack on a mother and a two-year-old boy who was left with a broken collarbone.
The boy, who was in a pushchair, was hurt when his mother was pulled by the hair and dragged to the ground at Walthamstow Central station on Sunday.
The woman, who is black, was racially abused by the man, police said.
A 47-year-old man from Highams Park was arrested by British Transport Police (BTP) at his home on Friday morning and is currently in custody.
He was arrested on suspicion of racially aggravated assault causing actual bodily harm and racially aggravated assault causing grievous bodily harm.
Police had previously described the attack as "unspeakable".
A BTP spokesman said: "I'd like to thank members of the public for coming forward with information, as well as the media for the overwhelming response which has greatly assisted with our investigation.
"The 47-year-old man currently remains in police custody helping detectives with their ongoing enquiries."
