An American law enforcement official who was briefed on the investigation said it appeared the liquid to be used was a peroxide-based solution to be detonated by an electronic device that was not specified, but could be anything from a disposable camera to a portable digital music player.
CNN states some of them worked AT Heathrow airport.

WASHINGTON (CNN) --
ARTICLE SNIPPET: "Two of the suspects recently traveled to Pakistan and later received money wired from there, senior U.S. government sources said.
Among those arrested were a Muslim charity worker and a Heathrow Airport employee with an all-area access pass, according to Britain's Channel 4.
The suspects were planning to stage a test run within a couple of days, said a U.S. intelligence official."
ARTICLE SNIPPET: "A senior congressional source said it is believed the plotters planned to mix a British sports drink with a gel-like substance to make a potent explosive that could be ignited with an MP3 player or cell phone." (
ARTICLE SNIPPET: "The sports drink could be combined with a peroxide-based paste to form a potent "explosive cocktail," if properly done, said a U.S. counterterrorism official.
"There are strong reasons to believe the materials in a beverage like that could have been part of the formula," the official said.
As many as 50 people were involved in the plot, an internal Department of Homeland Security document said, and raids continued in Britain late Wednesday."
ARTICLE SNIPPET: "Pakistani authorities also made arrests in coordination with Britain, said a spokesman for the Pakistani Foreign Ministry. He did not say how many arrests were made.
Two of the suspects left "martyrdom tapes," according to sources familiar with the details of the British investigation."
