Mohammed Jamil Asha, 26, was charged with conspiracy to cause explosions, a police spokeswoman said on condition of anonymity, in line with force policy. Asha was detained on a northern England highway June 30. His wife, Marwa Asha, was arrested on the same date, but later released.
Asha is the fourth person to be charged since a pair of cars packed with gas cylinders and nails were found in central London on June 29. The next day, two men crashed a flaming Jeep Cherokee loaded with gas canisters and gasoline into security barriers at Glasgow airport's main terminal.
Asha will appear in a London court Friday.
In Jordan, Jamil Asha — Asha's father — said he had no comment, and Jordanian officials also declined comment.
First to be charged was Dr. Bilal Abdullah, allegedly a passenger in the Jeep. He was also charged with conspiring to set off explosions.
Last week, police charged Indian doctor Sabeel Ahmed, 26, with withholding information that could prevent an act of terrorism. He was arrested in Liverpool the day of the Glasgow attack.
His brother, Kafeel Ahmed, is believed to have set himself ablaze after crashing into the airport and remains in a Scottish hospital with critical burns.
Muhammad Haneef, 27, a distant cousin who once shared a house with the Ahmed brothers in Britain, has been charged by Australian police with supporting a terrorist group.
A magistrate granted Haneef bail Monday, ruling the evidence did not justify holding him in custody. Hours later, the Australian government canceled his visa on character grounds and said he would be detained on immigration violations if he posted bail.
The formal charge says Asha "unlawfully and maliciously conspired with Bilal Abdullah, Kafeel Ahmed and others unknown to cause explosions of a nature likely to endanger life or cause serious injury to property."
In all, police detained eight people in the aftermath of the foiled attacks. Four have been charged, three released, and Kafeel Ahmed is under guard in hospital.
