Hundreds of police are involved in the security operation at the Limbecker Platz mall, which was locked down before it opened to the public, Essen police spokesperson Christoph Wickhorst said. Police officers and vans surrounded the mall -- one of the biggest in Germany -- Saturday afternoon, Reuters reported. But the closure comes a day after police received very serious indications from "another agency" that an attack was possibly planned on the mall Saturday, Wickhorst said. The apartment search is directly related to the mall threat, police spokesperson Peter Elke told German broadcaster NTV. A second man who was picked up at an Internet cafe was also being questioned, said police, who intend to search his apartment.
