"The two 27-year-old brothers are strongly suspected of taking part in the January 25 robbery of the luxury department store,” a Berlin police department statement said.
The men were picked up by a mobile commando team of Berlin police in the town of Rotenburg. A search also revealed evidence that still needs to be reviewed, police said.
“We have had more than 70 tips from the public,” the statement said. “The investigation with police and the state prosecutor's office is ongoing.”
In what has been described as one of the most spectacular heists in post-war German history, thieves used a ladder to climb onto a projecting roof on the Ansbacherstrasse side of the grand old store. They relieved the massive shopping paradise of €6 million in jewellery and luxury watches.
CCTV evidence suggests that three masked men then took their loot in two stages, using the projecting roof to store the valuables while they returned to get more. Police are still trying to work out why no alarms were triggered during the robbery.
