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. In Hesse alone last year, telephone fraud caused a total loss of 19.7 million euros. Seniors are popular victims because criminals hope to be able to grab more assets from this target. In Germany, older people are often the target of criminal con artists.
