BERLIN (Reuters) - German federal police have arrested a 19-year-old Algerian refugee who had fled a psychiatric facility on Wednesday yelling, "I'll blow you up," a police statement said early on Thursday.

The man was arrested at the Bremen main train station after an hours-long manhunt that prompted the evacuation of a Bremen shopping center, according to police in the neighboring state of Lower Saxony, who spearheaded the search for the man.
