This is getting just a bit too spooky for me.
Some of the report...
LONDON, England (CNN) -- British police say they have detained four more terrorism suspects near Heathrow airport, where the army has deployed hundreds of troops because of fears of an attack.
It is unclear if the arrests are connected to the discovery of a grenade in a Venezuelan man's luggage at London's second airport, Gatwick.
Police refused to give details about the latest suspects or to say if any weapons were found. They declined to say whether the arrests were connected to the security alert at Heathrow and in the London area since Tuesday.
The latest four people were arrested on Thursday directly under the flight path into Heathrow airport, at Langley, Buckinghamshire, officers said on Friday. They are being held under anti-terrorism legislation.
Meanwhile on Friday, Heathrow's Terminal 2, which deals mostly with flights to and from Europe, was evacuated -- and later reopened -- while a suspect package was examined.
British anti-terrorist police also continued to question the Venezuelan man to find out how and why he flew halfway across the world to London with the grenade.
He was arrested at Gatwick on Thursday after his luggage was searched by Customs officers. He had just stepped off a British Airways flight that took off from the Venezuelan capital Caracas and stopped off in Colombia and Barbados en route to London.
It was unclear where the 37-year-old man boarded the BA flight 2048, a Boeing 777 with 125 passengers on board.
British police, already on a heightened state of alert following reports of an imminent terror attack, closed the airport's north terminal and evacuated hundreds of passengers.
The terminal remained closed for more than four hours, wreaking havoc at Britain's second busiest airport and forcing hundreds of travellers to sleep in the south terminal or find hotel rooms.
"We've had to cancel 32 flights in all, which would probably affect around 2,500 passengers," a British Airways spokesman said, adding that the delays were bound to drag on through Friday morning. Other airlines were similarly affected.
BA re-routed its scheduled Friday flight to Caracas, saying the plane would fly only to Colombia and Barbados.
The BA spokesman said the measure had been taken "as a precaution" and added that the airline was conducting its own investigation into how the grenade passed undetected through South American security checks.
