ATHENS, Jan. 11 (Xinhua) -- More suspicious letters were delivered on Friday to six separate campuses in Greece, a few hours after the collection of 12 suspicious envelopes from universities around the country.
Universities and Technological Educational Institutes (TEI) of Ioannina, Rethymno, Patra, Lamia and Corinth received similar envelopes, as well as the private Mediterranean College in Thessaloniki, Greek national news agency AMNA reported. Police were informed immediately and took all appropriate measures to protect the citizens.
A suspicious envelope from India, addressed to the University of Ioannina rector's office, arrived on Friday morning by post, while a second one was detected at the TEI in Patras. Two more envelopes from India, arrived earlier on Dec. 28, 2018 at the TEI of Lamia, were found to contain advertising materials.
The envelopes were sent to National Centre for Scientific Research Demokritos and the General State Chemical Laboratory in Athens for analysis.
On Thursday a total of 12 envelopes, which in some cases contained a suspicious substance, were sent to universities around Greece. The targeted institutions were in Athens, the islands of Crete, Lesvos, Cephalonia and Corfu, the northwestern town of Arta, Sparta in the Peloponnese area and the coastal port city of Volos in Thessaly.
According to the results of a state lab examination, the powder traced was made of "irritants used in the production and improvement of adhesives and printing ink," AMNA reported.
Five people at the University of the Aegean on Lesvos Island were hospitalized with minor health issues, mainly irritation in the mouth, nose and eyes and were released on Thursday afternoon.
For precautionary reasons, several staff members who came into contact with the suspicious packages have already been subjected and will be subjected to further examinations.
