The father of a July 7 bomber's widow suspected of being part of a terror cell has begged her to "get in touch".
Andy Lewthwaite, 56, pleaded for his daughter to contact her family as police in Kenya hunted a woman using several identities, including that of Samantha Lewthwaite, 28.
But he insisted Ms Lewthwaite, who was married to King's Cross suicide attacker Jermaine Lindsay, would not be embroiled in terrorist activity.
The mother of three, originally from Aylesbury, Buckinghamshire, is reportedly travelling with her children.
Builder Mr Lewthwaite told The Sun: "I just wish she would get in touch with us."
He has not seen his daughter for months and said the family had not heard from her for some time.
"Samantha would not be involved in anything to do with terrorism," he said.
"She was badly affected by what happened before and would have nothing to do with it. I am sure of that."
Kenyan officers believe Ms Lewthwaite was most recently using the name Natalie Faye Webb and carrying a forged South African passport.
She is believed to have evaded capture when authorities carried out a raid on a group suspected of planning a terror attack in Mombasa over Christmas.
Ms Webb's father John, of Southend, Essex, told the newspaper of his fear after officers issued their arrest warrant in the name of his own daughter, an "innocent bystander".
"What is most terrifying is that the Kenyan authorities only knew this woman as Natalie, so the arrest warrant was put out in my daughter's name," he said.
"It is a relief attention can now focus on this woman."
Scotland Yard said it had sent a team of officers to Kenya to assist authorities with a terror-related incident in recent months.
Ms Lewthwaite converted to Islam at the age of 15 and married Lindsay in 2002 before he killed 26 people when he blew himself up in July 2005.
A police spokesman in Nairobi said: "We do not know it is her (Ms Lewthwaite)... we know she has (several) identities."
The Metropolitan Police has refused to discuss the extent of its involvement in the operation.
