Analysis of 31 suspicious envelopes shows only irritant substance, authorities say

After the completion of an analysis on 31 suspicious envelopes sent to Greek universities and other institutions, and with only four remaining to be tested by the General State Chemical Laboratory, the General Secretariat for Civil Protection on Monday announced that only a relatively harmless irritant substance has been detected so far, which poses no threat to human life.

None of the envelopes contained anything truly dangerous but all of them had traces of the same irritant that caused symptoms in the staff handling the letter that arrived in Mytilene, Lesvos, triggering fears of a possible terrorist attack, including one sent to the Patras Technological Educational Institute (TEI) from Doha, Qatar.

Nearly all the envelopes had been posted from India, apart from that sent to the Patras TEI and a second sent to the administration building of the Moria migrant and refugee camp in Lesvos from Oman.

Apart from the staff in Mytilene, none of the other people that came into contact with the envelopes have reported any symptoms.

The four that have not yet been examined are two envelopes sent to the University of Crete in Iraklio, the envelope sent to Corfu and that sent to the camp in Moria, which have not yet reached Athens.

Meanwhile, the counter-terrorism services is continuing an investigation to collect evidence that may lead to the discovery of who sent the envelopes and their real motives.
