"I saw him in the summer of 2006 on a visit to Jordan," said the friend, who asked not to be named. "He seemed really influenced by Islamist ideologies in Britain. Even physically he looked different with a long beard."
Some counterterrorism investigators suspect Asha is the ringleader of the terror cell and the mastermind behind the attacks.
Marwa Dana Asha
Marwa Dana Asha, 27, from the Palestinian territories, was arrested with her husband, Mohammed, on the M6 motorway. Asha also excelled as a student and studied at the elite Jubilee School in Amman, Jordan, where she met Mohammed, her high school sweetheart. In England, she is believed to have worked at the Royal Shrewsbury Hospital as a laboratory technician.
Her father, Younis Dana, called her arrest a mistake. He described her as an educated woman who would never be involved in extremist activity.
"She has always been religious but tolerant," Dana told the Daily Telegraph. "She wears the hijab but is open-minded and does not mind people who dress in a different way."
Sabeel Ahmed, 26, was arrested by police under the Counter Terrorism Act as he drove through central Liverpool Saturday evening. He studied medicine in Bangalore, India. In England, he worked as a locum (temporary position) at Warrington and Halton hospitals, both part of the North Cheshire NHS trust.
His mother, Zakia Ahmed, told The Associated Press that he and Mohammed Haneef were related, but she did not give details. She also said they both attended medical school together.
Mohammed Haneef, a 27-year-old Indian national, was arrested at Brisbane International Airport in Australia while trying to board a flight for India with a one-way ticket. He was arrested in connection with a phone call to a suspect in the United Kingdom.
Haneef studied medicine at Rajiv Gandhi Health University in Bangalore from 1997-2002, university registrar S. Sachhidanand told The Times of India.
He had been working as a junior doctor at the Gold Coast Hospital in Southport, Queensland, since September. Haneef previously worked at Liverpool's Halton Hospital in northwest England, where Sabeel Ahmed had also been employed.
