British police charged a 12th suspect today over an alleged plot to blow up US-bound airliners.
Umair Hussain, 24, was charged with failing to disclose information that could have prevented a terrorist attack, police said.
He is due to appear in a London court tomorrow. British police announced on August 10th they had thwarted a plot to blow up US-bound airliners over the Atlantic by smuggling liquid explosives onto flights.
On Monday, prosecutors charged eight British Muslims with conspiracy to murder and preparing acts of terrorism. They were accused of plotting to smuggle parts of home-made bombs on to planes, then build the bombs and detonate them.
A 17-year-old was charged with possessing items useful to a terrorist, including a book on home-made bombs, suicide notes and wills "with the identities of persons prepared to commit acts of terrorism", prosecutors said.
Two other suspects, including the mother of an 8-month-old baby, were charged with failing to report the plot. Mr Hussain's lawyer, Tim Rustem, said he and his client were surprised and disappointed the police had decided to charge him.
"I will be challenging the decision as quickly as possible," he told reporters. Mr Rustem said Mr Hussain had told him to file a complaint about his treatment in police custody because of alleged strip-searching and "the impression ... that we got that some parts of his private legal consultations may have been illegally monitored".
In response, a police spokeswoman said: "Any allegations we receive, we would look at."
Eight other people remain in custody who have not so far been charged. Detectives have until next Wednesday to question them. As many as 17 people are also being held in Pakistan over the suspected plot, including at least two British nationals.
The charges come 13 months after four British Islamist suicide bombers killed themselves and 52 other people at rush hour on public transport in London.
Police said this week they had seized "martyrdom videos", an apparent reference to testaments by would-be suicide bombers, as part of a huge investigation into the suspected aircraft plot.
The British government imposed tight restrictions on carry-on baggage by airline passengers for several days after August 10th, causing chaos at major airports at the height of the summer holidays.
