Police today revealed they are hunting Anis Amri, 23, a refugee who came to Germany earlier this year. His paperwork was found in truck's footwell.
He is probably armed, 'highly dangerous' and a member of a 'large' Islamic organisation and has weapons training abroad, security sources say.
Amri, who was born in the desert town of Tataouine in 1992 – a well-known ISIS stronghold close to the Libyan border - was apparently recently arrested for GBH [Grievous Bodily Harm] but vanished before he could be charged.
The refugee has temporary permission to stay in the country but was due to face an asylum hearing.
Police are believed to have found his blood in the truck's cab and now assume that the suspect may be badly injured.
Here's a German law that they might want to reconsider:
Despite an unfolding international manhunt the first pictures of him released in Germany have his eyes deliberately covered, thought to be because of strict privacy laws there. MailOnline has uncovered unblurred images.
