Another Suspect Arrested In Terror Case

British police say they've arrested another suspected in the plot to bomb as many as ten commercial flights from the UK to the US.

The arrest came Tuesday in the Thames Valley, where many of the other 24 suspects were seized. One of those initially detained has since been freed... so the total number of suspects still stands at 24. 

In the meantime... Britain's airport security nightmare continued into its sixth day Tuesday, marked by more delays and dozens of flight cancellations.

The British Airports Authority -- which manages Heathrow, Gatwick, Stansted, and four other airports -- may have been hoping that the government's slight relaxation of carry-on restrictions would ease the long lines at both ticket counters and security checkpoints... but that apparently hasn't happened.

CNN reports one in every two passengers is still being pulled aside for additional screening. At Heathrow alone, 40 flights were cancelled because of problems caused by the new restrictions. Another 11 were cancelled at Gatwick.

BAA chief Stephen Nelson says there are plenty of personnel on duty to handle the huge job of searching every other passenger... but that claim is coming under increasing fire from the airlines.

"Since 9/11, everyone in the industry has known there might be times when extra security measures needed to be put in place," said British Airways chief executive Willie Walsh to the Daily Mirror. "Yet when the moment struck, BAA had no plan ready to keep Heathrow functioning properly."

Ryanair CEO Michael O'Leary agreed, adding the UK government "failed to provide any leadership" in the days after last Thursday's arrests.
