One of seven people arrested over an alleged plot to launch a terrorist attack in Britain has been released without charge, police said Sunday, as detectives continued to question more than a dozen other people over two alleged plots.
The Metropolitan Police said the 30-year-old woman detained in London on Thursday has been freed.
Five men and a woman are still being questioned over allegations of “the commission, preparation or instigation of acts of terrorism.”
The suspects include a British Muslim convert who once appeared in a documentary about Islamist extremism and three brothers who were detained by armed police at their home near London’s Olympic Park.
Counter-terror officers are on high alert ahead of the Olympics, which begin July 27, but police say the arrests are not connected to the Summer Games.
