No fewer than 14 migrants from nine countries were arrested by the Italian authorities in Rome on Monday, for their alleged involvement in unrest spurred by the death of a Guinean migrant.

The migrants were arrested in a repatriation centre as they began to burn mattresses and hurl objects at the law enforcement agents, according to AP.

The report revealed that the body of the 21-year-old Guinean migrant was discovered at the centre on Sunday morning.

Meanwhile, an Italian lawmaker Riccardo Magi told La Repubblica television, that the migrant hung himself after expressing desperation over his inability to join his family in his home country.

In reacting to the death of the migrant, others pained by the incident resolved to vent their grievances as some used phone booths to knock down two partitions. 

Police said one group reached parked police vehicles, setting one on fire, while another group entered a room where law enforcement personnel kept personal items, which they took and destroyed. The suspects also destroyed eight video cameras.

Authorities used tear gas to calm the unrest, which lasted into the evening. Three officers were injured.

The suspects are from Morocco, Pakistan, Guinea, Cuba, Chile, Senegal, Tunisia, Nigeria and Gambia, police said.

Reacting, the lawmaker Magi said, “These centers are black holes for rights and humanity. Most people who are being held here will never be repatriated.”
