John Travolta and Kelly Preston arrived at court with a security escort

Former senator Pleasant Bridgewater and medic Tarino Lightbourne are accused of demanding money from the star after his son died in the Bahamas in January.

They allegedly wanted $25m (£15m) in return for keeping secret a document relating to 16-year-old Jett's treatment. The pair deny the charges.

Since the death of his son, the actor has rarely appeared in public.

Ms Bridgewater resigned her seat on the Bahamas senate after she was arrested in January. Mr Lightbourne was one of the paramedics（军医） who responded when Mr Travolta's son was taken ill.

John Travolta and his wife Kelly Preston arrived at Nassau Supreme² Court on Wednesday with a large security escort（护送，护卫）.

Nannies

The court was told that Mr Travolta and Ms Preston had travelled to a resort on Grand Bahama with Jett and their eight-year-old daughter, Ella, accompanied by four nannies（保姆）.

The actor began his testimony³ by recalling the moments before his son's death.

He said he had been woken by one of the nannies pounding on his door and had run downstairs to find his son on the bathroom floor and one of the other nannies trying to resuscitate⁴（使复活，使苏醒） him.

Mr Travolta said he took over the resuscitation⁵ attempts helped by a visitor at the resort.

The actor told the court his son was autistic（自闭的） and suffered from seizures⁶（癫痫）.

Earlier, police inspector⁷ Andrew Wells told the court that Mr Travolta had wanted his son flown to the US instead of the nearest Bahamian hospital.

He said Mr Lightbourne had wanted a signature on a statement confirming that Mr Travolta waived⁸（免除） medical treatment for his son.

Mr Travolta said he was so intent on saving his son that he signed the medical liability（医疗责任） release document - which is thought to be the subject of the alleged¹ extortion（敲诈，勒索） - without reading it.

Bahamas prosecutor⁹ Bernard Turner testified on Tuesday that Mr Travolta had been threatened with the release of potentially damaging statements if money was not paid.

The case continues.
