Police explode car at hospital holding fire bombers

CNN:

A controlled explosion has been carried out on a vehicle at the hospital treating a suspect in the attack on Scotland's busiest airport.

A police spokesman told The Associated Press: "It is believed that this car is connected to yesterday's incident at Glasgow International Airport."

Police also raided several buildings in the town of Newcastle-Under-Lyme, a town in central England between Manchester and Birmingham. ( Watch the latest on the investigation »)

The developments came after Britain raised its terror alert status to the highest level of "critical," indicating an attack is imminent and the country's prime minister warned of dangers to come.

In Scotland, officers swooped on a "number of houses" in an operation they said was linked to both Saturday's airport attack and the London bombs.

In the latest in a series of arrests, one person was seized in the northwest city of Liverpool and two houses were searched. Two people, said to be a 26-year-old man and a 27-year-old woman, were earlier arrested in nearby Cheshire on the Glasgow-bound M6 highway.

In the small Scottish village of Houston, just outside Glasgow, video footage showed police combing a three-bedroom rental house. Neighbors described the occupants as of "Asian" appearance.

I did not know there was a Houston in Scotland.

The police work appears to be pretty comprehensive investigating not only homes but any vehicles that are near where the suspects are being held. The search of homes is probably related to the suspects that have been arrested and clues that may have resulted from earlier searches of their homes. There is still no word on whether any of those arrested are ones being sought for violating their control orders.

The BBC reports that the investigation is very fast moving and that the forensic examination of the vehicles has yielded several clues. Fox New's Bill Hemmer reported that the two arrested in Cheshire had their clothing removed and bagged for examination for matches of fiber. Police in Scotland are receiving about 100 calls an hour on the case. They gave out the license number of the Jeep and asked those who might have seen it in recent days to contact them.
