A 22-year-old Moroccan national has been arrested two months after the attack on the museum left 21 tourists dead in March
Italian police investigating the deadly attack on a Tunis museum in March said on Wednesday they had arrested a Moroccan man who arrived in Europe on an illegal migrant boat.
Majid Touil, 22, was detained on Tuesday evening in the northern Italian town of Gaggiano. He was known to have travelled to Italy in February on a migrant boat, and was living with his mother and two older brothers near Milan.
"A Moroccan national, wanted internationally, was arrested yesterday evening in a town in the Milan region. The Tunisian authorities suspect him of having taken part in the Bardo attack," said a police spokesman.
