Police in Munich have said they received concrete evidence that a terror act was planned for New Year in the Bavarian capital. Investigators are not sure if the potential attackers remain in the city.
Munich police chief Hubertus Andrä told a news conference on Friday that German officials had received a "very concrete" tip that suicide attacks were planned in Munich.
He added that that there was now thought to be no "imminent danger," although it was unclear whether possible suspects were on the loose.
Andrä's comments came after the evacuations of both the central train station and a station in the western Pasing district, both among the possible targets, on Thursday evening. According to Andrä, five to seven people were involved in the possible plan.
Andrä claimed authorities had received the names of "roughly half" those suspects from a friendly security service. Syrians and Iraqis were said to be involved. However, Andrä said it remained unclear whether the information was true.
"We have examined data relating to these names, but at the moment, we do not know if these names are correct, whether these people exist and where they are," said Andrä.
'No false alarm'
The police chief added that the terror warning had been decreased to the level that it was at before the information was received.
"Overall I would say that the situation for Munich is as it was before this threat of attack," said Andrä. The police chief dismissed speculation that the threat had been a false alarm. "
"If there is such information, we have to act" he said. The stations reopened a little after 3:30 a.m. (0230 UTC), allowing trains to depart according to schedule.
Partial stand down
Some 100 extra security personnel were still deployed in the city on Sunday, with 550 additional police officers having been drafted in from across Bavaria to help in the evacuations. Security forces were patrolling city center streets and around train stations on Friday.
The extent of the security operation had been agreed "to show an appropriate presence and to suitably satisfy citizens' security needs," Andrä said.
"We still have significant police deployment at Munich central station and Pasing station but this has been significantly reduced compared to last night," said Bavarian Interior Minister Joachim Hermann (pictured above, right).
Meanwhile, German Interior Minister Thomas de Maiziere thanked all involved authorities for their "thoughtful, considerate and decisive" action in Munich on New Year's Eve.
