Via contra-info:

Here is the new address for comrade Nikos Maziotis:

Sending books to inmates is banned in Diavata prison, where Nikos Maziotis is currently incarcerated. So the comrade can only receive letters (at best some news reports too). It is obligatory to indicate a sender address, otherwise letters are not delivered.

To write to the comrade:

Nikos Maziotis
Geniko Katastima Kratisis Thessalonikis
57008 Diavata,
Thessaloniki,
Greece
