Mrs Pereira, 43, rom Nettlebed, has not been seen since a service at the Church of the Sacred Heart in Henley on Sunday, December 3. Officers say she may have travelled back to India, where she is from, or to Bahrain, where she has strong links.

Acting Det Insp Chris Biddle said: "We are still investigating all possibilities, but we are looking seriously at the prospect Maria may no longer be in the UK.
"There is someone who knows where she is or what has happened to her and we urge them to contact us. Equally if Maria has left of her own accord I beg her to call us and let us know she is okay."
