Parts of the western German city of Saarbruecken were under lockdown Sunday as police tried to convince an armed man to leave a restaurant Dubrovnik in which he had barricaded himself.
Police have had no direct contact with the man, who is believed to work at the restaurant. He did force a restaurant employee to leave the building, they said.
"It looks as if he's alone in there," a police spokesman told dpa.
Police said there does not seem to be a political motivation to the incident. There are reports that the man's clothing is blood-stained.
