“Czech authorities will provide five policemen to escort him during his flight back,” Pol Lt-General Nattorn Prohsunthorn, the chief of the Thailand’s Immigration Bureau, said yesterday.

Zdenek Pfeifer, 49, was arrested in Phuket last week in response to the request from Interpol and Czech authorities.

Interpol recently issued an alert about Pfeifer describing him, saying he “may be armed, infectious and is liable to commit sexual offence involving minors”.

The alert did not mention the nature of the infection but Thai police have implied that he might be HIV-positive.
