German police have arrested three suspects in connection with a €2.5 million burglary targeting Emma-Lou Becca, the 21-year-old daughter of Luxembourg tycoon Flavio Becca, thanks to her use of Bluetooth tracking.

According to reports from German newspaper Bild, Emma-Lou Becca, the 21-year-old daughter of Luxembourg real estate tycoon Flavio Becca, became the victim of a large-scale burglary in March, with jewellery, watches, and 40 designer bags stolen from her Munich apartment. The items, including several Hermès bags, are said to have a combined value of €2.5 million.

However, the young Luxembourger was able to help catch the perpetrators after noticing that her bluetooth headphones were left in one of the bags which she was subsequently able to trace and locate online. Police were thus able to apprehend three suspects in Ingolstadt – a 21-year-old man and two women, aged 39 and 43. All three are currently in pre-trial detention with the trial scheduled to start this week, according to Bild.

The Becca family lawyer has refused to comment on the case and the stolen bags have not been found yet, the German newspaper further reports.
