Munich police said officials had deemed the information about the threat of an attack on New Year’s Eve as serious and credible.
Authorities told the public additional officers were being called in to find possible suspects.
Another country’s intelligence agency reported the plot and the ISIS connection to German federal police, Bavarian Interior Minister Joachim Herrmann told journalists.
“The threat very specifically referred to midnight and to these two places,” Herrmann said.
Between five and seven alleged terrorists were planning suicide attacks, Munich police president Hubertus Andrä told journalists.
“The concrete tip this evening came from one source,” he said.
Investigators have not been able to find suspects or further clues to shore up the tip.
In light of the threat, police had requested that the public to stay away from large gatherings.
