[JURIST] UK police arrested a fifth suspect [press release] near Glasgow International Airport [official website] Sunday in connection with three terror incidents over the weekend. On Saturday, a flaming Jeep crashed [Sky News report] into the front entrance of the Glasgow air terminal. On Friday, police foiled two car bomb plots [press statement and recorded video] in central London. Scotland Yard [official website] arrested two people early Sunday on a major highway in northern England. Another person was captured overnight in Liverpool. The other two men were arrested in Scotland following the airport crash.

Four suspects are in police custody. The fifth was badly burned in the crash and is now under guard in a hospital. Officials believe the attacks were linked. Lord John Stevens [official profile], former chief of the London Metropolitan Police and now new Prime Minister Gordon Brown's [official profile] terrorism adviser, said the two attacks in Britain indicate that "al Qaida has imported the tactics of Baghdad and Bali to the streets of the UK." Britain raised its terror alert level [MI5 press release] Saturday to critical, the highest level possible. AP has more.
