BERLIN — German police urged residents of Berlin’s southern suburbs to stay indoors on Thursday, as they scoured the area for a wild animal on the loose, apparently a lioness. Two passersby who saw one animal chasing another,” Daniel Keip, Brandenburg police spokesman, told RBB radio. “One was a wild boar and the other apparently a wild animal, a lioness. Berlin police then alerted the public to the beast’s presence, initially putting the southwestern suburbs on alert and then expanding the area of the search. “The wild animal that escaped has not yet been found!” the police of Brandenburg, the region around Berlin, wrote on Twitter around 7:30 am (0530 GMT).
