A brother of the fugitive Tunisian suspected in Berlin’s deadly Christmas market attack is urging Anis Amri to turn himself in to police, The Washington Post reported.

Amri’s family members, speaking from his hometown of Oueslatia in central Tunisia, were shaken to learn he’s the prime suspect in Monday’s truck attack, which killed 12.

Amri, who turned 24 on Thursday, left Tunisia years ago for Europe but had been in regular contact with his brothers via Facebook and phone.

Brother Abdelkader Amri said told “I ask him to turn himself into the police. If it is proved that he is involved, we dissociate ourselves from it.”

Abdelkader said Anis may have been radicalized in prison in Italy, where he went after leaving Tunisia in the wake of the Arab Spring uprisings.
