The fatal accident occurred on the Appia highway in the southern Italian region of Campania.
The two young men – a 20-year-old from Guinea and a 19-year-old from Senegal – were cycling along the section of the highway that connects the town of Nola-Villa Literno to the city of Capua when they were hit and killed.
The driver, 42-year-old Antonio Corvino, fled the scene in his BMW X3, which was later found and seized from a car body repairs shop in the province of Caserta.
CCTV footage from businesses located along the road reportedly captured the incident.
Corvino is being detained in Santa Maria Capua Vetere prison and will be questioned by prosecutors in the coming days.
