Prosecutors investigating claims anaesthetic gas used to gas Jenson Button and wife during burglary
Anaesthetic gas may have been used against Jenson Button and his wife Jessica during a holiday burglary in France, the Formula 1 driver's spokesman has said.
The Formula One driver and his wife Jessica were burgled on holiday and "most upsettingly" the thieves made off with her engagement ring as well as other pieces of jewellery.
The Sun newspaper reported that valuables worth £300,000 were stolen.
"The police have indicated that this has become a growing problem in the region with perpetrators going so far as to gas their proposed victims through the air conditioning units before breaking in.
"Whilst unharmed everyone involved is unsurprisingly shaken by the events."
Philippe Guemas, deputy prosecutor in Draguignan, France, told Europe1 radio that "nothing has been established" and said the claim that gas was used in the raid was made by Button's entourage as the driver felt unwell the following day.
"To our knowledge there has never been a burglary like this in St Tropez where gas was used to knock out the victims," he said.
"We have taken blood samples, which will be analysed."
