Time for another egregious missed red flag about Abdulmutallab

The security services knew three years ago that the Detroit bomber had “multiple communications” with Islamic extremists in Britain, it emerged this weekend.

Counterterrorism officials said Umar Farouk Abdulmutallab was “reaching out” to extremists whom MI5 had under surveillance while he was studying at University College London.

Officials said the 23-year-old Nigerian was “starting out on a journey” in Britain that culminated in his attempt to bring down flight 253 as it prepared to land in Detroit, Michigan, on Christmas Day.
