My cousin Aziza went missing during a theatre trip in London with family yesterday. She has learning difficulties and I suspect just decided during the intermission that she wanted to leave and walked out without speaking to anyone.
She has no coat, phone, or money and it has now been more than 24 hours in freezing temperatures.
We are working closely with the police but would welcome any help in spreading the words in case someone remembers seeing her.
