The father of a teenager with autism who is quarantining in a hotel at Heathrow has said the experience has left his son depressed, physically unwell and unable to eat properly. Nelio Salles De Siqueira, a chef from Peckham in south London, said 16-year-old Caique Pires Salles will barely leave his bed after being forced to stay at the Holiday Inn near the airport following their return to the UK from Brazil. He spoke of his anguish at being unable to help as his son begged to be taken home, despite notes from his psychiatrist and school warning that the experience would be “psychologically unhealthy”.
