After the theft of millions from a money transport company in Stuttgart, the investigators are following numerous clues.
A police spokeswoman said on Tuesday that more than 150 tips had already been received from Germany and abroad.
These will now be checked.
A possible lead in the Balkans is also being pursued.
The police are looking for a 1.74 meter tall woman with blue-green eyes, blonde hair and tattoos.
She worked for the money transport company.
The police have not yet released any further details about the course of events.
The 42-year-old is said to have taken advantage of her job at the company and stole more than one million euros in October.
According to the police, a week ago, a 27-year-old stole another 135,000 euros from the same company.
The theft was therefore noticed on December 28th.
Investigations quickly traced the 27-year-old.
During a subsequent search of the home, neither the man nor the stolen goods could be found.
The 27-year-old then turned himself in to the police.
He is in custody.
Investigators are still looking for the money.
It is currently assumed that the two cases at the company are not related, said the police spokeswoman.
