Nine people are being questioned by police in connection with the shooting of the 14-year-old blogger Malala Yousufzai, who was attacked in Pakistan earlier this month as she travelled home from school.
Although the main suspect, 23-year Atta Ullah Khan, a chemistry student from the Swat Valley is still at large, his mother, fiancee and brother are all being questioned, reported CNN.
They are not suspected of the attack, a senior police chief from Pakistan told the broadcaster, but six other men have been arrested.
The Taliban claimed responsibility for the attack and said she will not be safe if she recovers. Malala is currently being treated for her injuries in Birmingham Queen Elizabeth hospital and is said to be responding well to treatment.
Malala wrote a blog for the BBC about atrocities committed under Taliban rule
Malala's father has spoken out for the first time since his daughter was shot, as he and his wife waited to board a plane to join their daughter in Birmingham.
He told The Daily Telegraph he would have flown over sooner but they had problems with their travel documents.
"I have seen doomsday and survived, you might say. Malala has been honoured by the nation by the world, by people of all classes of all creeds of all colours. I am grateful for that,"
Malala Yousafzai was brought to Britain for treatment
"But I am a father. I respect all those feelings but the only priority now is the life of my daughter and her total rehabilitation.
"I don't need any awards... I need my daughter."
Malala wrote under the pen name Gul Makai because it was too dangerous to reveal her real name
Schoolgirl Malala Yousufzai was only 11 when the Taliban banned girls’ education in the Pakistan's Swat valley in 2009.
More than 4,000 girls' schools were razed to the ground by the Islamist militant group. Girls who attempted to study lived in fear of being kidnapped, having acid thrown in their faces or even being killed.
At a time when even political leaders were terrified of criticising the Taliban, an 11-year-old schoolgirl found the courage to speak out.
"The decision to ban girls from going to school was shocking for me and I decided to stand against the forces of backwardness," she told news agency APP in January.
