One of three suspects detained in an alleged plot to extort $20 million from a grieving John Travolta has been formally charged, while another is said to be cooperating with police.

Bahamian Senator Pleasant Bridgewater was charged Friday afternoon with abetment to extort and conspiracy to extort, according to a police spokesman. She was then released from custody on $40,000 bail.

Travolta family friend and current member of parliament Obie Whilchcombe, who acted as an unofficial spokesman for Travolta and wife Kelly Preston in the wake of their 16-year-old son's death, was released on his own recognizance pending further investigation.

Ambulance driver Tarino Lightbourne, meanwhile, remained in custody late Friday and, per a police statement, is cooperating with the investigation.
