This gist is a bit belated, I learnt it happened in May. Spanish media, El Mundo reported that Maria Dolores dos Santos Aveiro,the mum to World best footballer, Cristiano Ronaldo was stopped 
stopped by the police in Madrid’s Barajas airport few weeks back for stacking €55,000 cash in her luggage.
Now, the Spanish law forbids passengers to travel with more than €10,000. During interrogation, she was unable to explain how she came about the cash and what it was for? The police were left with no option than to seize extra €45,000 from her. meaning she collected €10,000 and continued her journey.
El Mundo, gathered that she will now have to answer questions from the Spanish tax authority about the seized money.
