Police in eastern Germany say they're looking for three men from a suspected vigilante group after a video surfaced of them pulling an Iraqi migrant out of a supermarket.

Goerlitz police told the dpa news agency Thursday the 21-year-old Iraqi was arguing with supermarket employees over a defective phone card on May 21 in Arnsdorf when three men in black shirts stormed in, grabbed him, took him outside and zip-tied him to a tree.

The men fled when police arrived.

Bild newspaper on Thursday posted a video of the incident, which it said has been making the rounds on far-right websites.

Police are looking for witnesses who can identify the men. They're also investigating the migrant, who supermarket workers said threatened them with a bottle.

Authorities in Greece say three migrants have been hospitalized with injuries after violence broke out overnight at a detention camp on the island of Lesbos.

The clashes between migrant groups occurred early Thursday and also resulted in a fire that gutted a converted freight container used as trailer home, police said.

It was the latest violence at the Moria camp on the Greek island, where more than 2,500 are held in detention following a March agreement between the European Union and Turkey to deport migrants and refugees.

Deportations have been held up by delays in the asylum screening process — triggering frequent unrest at camps on Lesbos and the nearby island of Chios.
