Berlin terror attack: Tunisian suspect was investigated over earlier terror plot

A dangerous" Tunisian man with ties to Islamic extremists who has been identified as a suspect in the Berlin lorry attack which left 12 dead.

Anis Amri has been identified by Tunisian officials as the man being sought by German police across the country and the wider border-free area of the European Union, and a 100,000 euro (£84,000) reward is being offered for information leading to his arrest.

It emerged the 24-year-old was put under covert surveillance by German authorities for more than six months after they received a tip in March that he may have been planning a break-in to finance buying automatic weapons for an attack.

But agencies stopped watching him in September after nothing was found to substantiate the original warning.

German Interior Minister Thomas de Maiziere said Amri was suspected of involvement in Monday"s terrorist outrage but was not necessarily the man who drove the hijacked lorry into a crowded Christmas market in the German capital.
