Driver Lukasz Urban, a Polish citizen, was found dead on the passenger seat with gunshot and stab wounds.

Investigators believe the lorry was hijacked on Monday afternoon as it stood in an industrial zone in north-western Berlin, Germany's Bild tabloid reports.

Mr Urban had stopped there after the delivery of Italian steel beams he was carrying was postponed until Tuesday.

GPS data from the vehicle reportedly shows it made small movements "as if someone was learning how to drive it" before leaving for the city at 19:40 (18:40 GMT), heading for the Christmas market near the Kurfuerstendamm, Berlin's main shopping street.
