Pensioner cheated out of her fortune with a retro trick - police with four elementary warnings. Pensioner handed over 10,000 euros to a supposed police officer - because she thought she could help her son.

The police give three warning signs on how the fraud can be exposed. Seniors are popular victims of fraudsters: consumer advice centers also warn. In Hesse alone last year, telephone fraud caused a total loss of 19.7 million euros. The investigation has begun, but the perpetrator has not yet been caught.
