PARIS (AP) -- A second stadium in the northern German city of Hannover has been evacuated.

Concert-goers had been waiting for the band "Soehne Mannheims" to play.

Hannover's chief of police says authorities received a warning about a possible bomb threat shortly before the start of a soccer friendly match between Germany and the Netherlands in the main Hannover stadium. The stadium was evacuated and the game was canceled.

Police chief Volker Kluwe told German public broadcaster NDR that the alleged threat involved the "detonation of explosives in the stadium." He says the "key warning reached us about 15 minutes before the gates opened."

Germany's national soccer squad said the team was taken to "a safe place" by police.

Kluwe encouraged people in Hannover to go home, stay away from stadiums and not move about in large groups.

Germany's top security official says the decision to cancel the soccer match between Germany and the Netherlands was made after authorities received mounting information during the course of the day about a possible attack.

Interior Minister Thomas de Maiziere told reporters he wouldn't name the source of the information that led to the match in Hannover being called off shortly before it was to take place. German Chancellor Angela Merkel had been among the top Germany officials scheduled to attend.

The German news agency dpa cited unnamed security officials in Berlin that a foreign intelligence agency had warned Germany of a possible attack by Islamic extremists.

Germany's interior minister was holding a news conference later Tuesday on the twin evacuations.
