Osama Bin-Laden believed spies implanted surveillance chip in wife's teeth

A CACHE of private letters sent to the terror chief's loved ones reveal the extent of Osama bin-Laden's paranoia as al-Qaida crumbled.

   MURDERER: Osama bin-Laden's personal letters have been released

The evil September 11 mastermind warned his wife not to visit hospitals or dentists over fears they were bugging her teeth, it has been revealed.

Suspicious that she had been released by her Iranian captors, the al-Qaida leader picked up a pen to warn her it could be part of a ploy. 

He advised her that a dentist may have implanted a chip "the length of a grain of wheat" so the government could spy on her after her release.

He told her: "They can insert a small chip in it to implant under the skin.

"The size of the chip is about the length of a grain of wheat and the width of a fine piece of vermicelli.

"I would like you to tell me the reasons they mentioned to you for your release and every detail to help me from the security point of view.

"I need to know the date you had the filling, also about any surgery you had, even if it was only a quick pinch."

Clearly sceptical that she had been freed, he squeezes her for as much "boring" detail as possible, adding that "if you cannot remember the date, it is fine to give me approximation".

Afraid his hide-out would be foiled through communications with his lover, he instructed her to remain in good health and avoid hospitals or dentists at all costs.

"Please take care of all your medical needs, particularly teeth, and keep the prescriptions after you get the medicine, that easy you can refill the prescription when you come to us, God willing, when needed," he added.

The note is part of a dossier recovered by US forces after they raided bin Laden's compound in Abbottabad, Pakistan.

It includes a £20million will left to jihadis to fund future terrorist attacks. 

It revealed a paranoid side to the man who plotted the hijacking of four passenger planes — two of which flew into the World Trade Centre in New York.

Apologising for a lack of communication — blamed on having a sick post officer — he asked his wife "do you have heating?" adding that "everybody here is looking forward to your arrival, and they give you their regards".
