Burglars used some form of sleeping gas to knockout Jenson Button and his wife before robbing them of at least $400,000. That includes Jessica’s engagement ring reportedly worth $387,000.
The French police have indicated that this has become a growing problem in the region with perpetrators going so far as to gas their victims through the air conditioning units before breaking in robbing their victims
French police believe the gang had been watching the villa for days before letting off a canister of anesthetic gas into an air-conditioning vent.
Thieves slip through balconies or open windows and direct the sedative into bedroom air-conditioning units to knockout their intended targets.
The criminals wear masks to avoid being affected by the gas before ransacking their victim’s home and stealing any valuable property.
In 2010, British women Lisa Smyth reported that she and her son were drugged and robbed at the family home in Valbonne, southern France.
French police have previously blamed the activity on Russian or Romanian gangs, who target the conspicuously wealthy.
