He is said to have walked out of his room while his parents slept.

The parents were reportedly arrested in the aftermath, but later released.

A hotel manager was also arrested, but was also freed, it is claimed.

A Greek police source told The Sun: "It is common for next of kin to be arrested in such circumstances but as is always the case, they were not held in police custody and were immediately freed."

Media reports in Greece claim the child died before paramedics were able to get him to hospital.
