(ANSA) - Salerno, January 11 - A train conductor on a regional rail line in Salerno province was hospitalized Monday after being attacked by a group of Nigerian asylum seekers, Carabinieri police said Monday.

Four suspects aged 25-30 were arrested and are being questioned with the help of translators and cultural mediators from the migrant reception center where they live.

The attack took place on the publicly-owned Trenitalia Mercato San Severino-Buccino line after the conductor asked the suspects, who boarded at Eboli, for their tickets.

They responded by pushing, kicking and slapping him, continuing the assault on the station platform while another fellow Nigerian filmed the entire thing on his cell phone.
