The wife of the former British ambassador to the US, Sir Christopher Meyer, has told the BBC her husband is in hospital after being attacked at a station in London.
Lady Catherine Meyer said he was going home via Victoria Station on Wednesday afternoon when the attack happened.
She said he may have a broken nose and his eye was swollen “like a balloon”.
Police said two teenagers had been arrested on suspicion of assault occasioning grievous bodily harm.
A 16-year-old boy from Hillingdon and a 15-year-old girl from Croydon have been released under investigation while enquiries continue.
Lady Catherine said: “I am a wife who is angry that her husband has been beaten badly.
“As you get older it’s harder to recover from this sort of thing.”
British Transport Police urged any witnesses to the incident to call them on 0800 40 50 40 or text 61016, with the reference 334 of 11 July.
