John Travolta claims a paramedic threatened to blame him for his son's death unless he handed over £18 million [ million]. The 55-year-old actor told a court in Nassau, in the Bahamas, Wednesday that paramedic Tarino Lightbourne said he would accuse John of killing 16-year-old Jett unless he was paid the huge sum.

Travolta claims Lightbourne threatened to "imply that the death of my son was intentional and I was culpable in some way."

Lightbourne and his attorney Pleasant Bridgewater are jointly accused of attempting to extort and conspiring to extort by means of threats, charges they both deny.

Travolta has previously told the court how he attempted to save his son's life after he suffered a seizure at the family's Caribbean home on January 2, 2009.
