* Police are expected to arrest four pupils at a west London school after they were allegedly filmed attacking a French woman.
The 18-year-old was racially abused and punched by a gang of about 20 teenagers as she walked near Hurlingham and Chelsea secondary school in Fulham at about 3.20pm on Wednesday, January 12.
Pupils filmed the attack on their mobile phones and police believe they have identified four suspects, three girls and a boy, from the footage.
London Transport Police said it had already charged eight people who had committed happy-slap-style attacks on commuters.
