“Greek and foreign organisations for human rights but also, more recently, the mayor of Acharnes have reported that conditions at the Amygdaleza concentration camp are inhuman and humiliating, a fact made worse by the high temperatures,” the party said.

SYRIZA called for the immediate launch of an investigation to determine whether migrants were beaten when police units entered the facility to quell the riot .

The party also called for the immediate closure of camps and their replacement with hospitality centres for migrants and refugees needing international protection.

Meanwhile, the Greek police has denied that conditions for detained migrants at the Amygdaleza  center in Athens were unsuitable after a riot broke out on Saturday and 10 immigrants escaped from the facility, according to Kathimerini.

“We take all the necessary measures so holding conditions are respectable and that there is no chance of escape,” police spokesman Christos Parthenis told Mega TV.

Riot police were dispatched on Saturday to put down a riot at Greece’s main migrant detention camp where detainees hurled stones at officers and set fire to their living quarters, authorities said, AFP writes.

Violent riots broke out at the centre late on Saturday night and continued until the early hours of Sunday morning.

Television footage showed fires blazing at the Amygdaleza detention camp outside Athens, where some 1,200 mainly Asian migrants are kept under police guard.

Amygdaleza is one of several detention camps set up since last year to assist in the repatriation of thousands of undocumented migrants.

The police spokesman said rioting began when the detainees were told that their maximum stay in the camp would be extended to 18 months from a year previously.

According to AMNA, during a head count on Sunday, ten of the foreign nationals being held at the facility were found to be missing.

According to Greek media reports, the second temporary detention or so “closed hospitality centers”, is going to start operating near the small town of Deskati, in the northern prefecture of Grevena, after the May 6 elections.

Local residents are open to the project however, unlike residents in Amygdaleza, according Deskati Mayor Nikos Migos. “The local community does not only believe that the center will not be a problem but that it will bring us significant benefits,” Migos told Kathimerini, referring that  the facility would create 150 police jobs, 350 more jobs for guards and another 350 in other sector

Meanwhile, in a new statement to address illegal immigration, Mr. Chrysohoidis announced on Tuesday that it will raid apartments, mainly in central Athens, where thousands of undocumended immigrants live in overcrowded and unhygienic conditions. The minister warned that property owners of these overcrowded apartments of sometimes “30 or 50 people in crammed spaces of 50 to 100 square meters” illigal immigrants will be arrested.

On radio, Minister of Citizen Protection said that “Athens will BE clear in a few days, today or tomorrow  we will announce that the apartments in which undocumented immigrants live en masse will be empty and the owners prosecuted.”
