The Royal Borough of Greenwich told BBC London it was aware of concerns surrounding "experimental procedures" on autistic children.

A spokesperson said the authority had recently been made aware of concerns that "an individual claiming to be a doctor plans to visit the UK to offer dangerous, experimental procedures on children with autism".

"We understand that this person is proposing the transfer of bone marrow and spinal fluid to the brain by injection," the spokesperson said.

A spokesperson for the Met Police said: "Inquiries are ongoing to establish the identity of the person(s) behind these adverts and to confirm where they are based.

"We would encourage anyone looking for advice or guidance about autism to seek reliable and safe information from our charity, the NHS and the National Institute for Health and Care Excellence."
