Report: Widow of London bombings suicide attacker sought in Kenya plot

London's Times newspaper reported on a suspected terrorist plot in Kenya Wednesday.

Updated at 11:17 a.m. ET: LONDON -- A woman believed to be the widow of one of the four suicide bombers that killed 52 London commuters in July, 2005, is being sought by Kenyan authorities in relation to a terrorist plot in that country, The Times newspaper reported on Wednesday.

Kenyan police were searching for a woman who evaded them when they tried to capture members of a group thought to be planning an attack on the city of Mombasa in December, 2011, the newspaper reported. (The Times operates behind a paywall.)

One of the identities the suspect was believed to be traveling under was Samantha Lewthwaite, the widow of Jermaine Lindsay, who blew up a subway train at King's Cross station on July 7, 2005, Kenyan police told The Times.

The suspect had claimed to be Natalie Faye Webb, a South African, but the passport with this name was determined to be fake, the newspaper reported.

A Briton from east London has been charged in Kenya with possession of illegal explosive material and plotting to detonate a bomb. Jermaine Grant, 29, was arrested with three Kenyan men. Police are investigating possible ties with the Islamist group al-Shabab in Somalia. Ch4 News' Jonathan Rugman reports.

Lindsey's backpack-borne bomb claimed 26 lives on 7/7, as the attack is known in the U.K.

A Kenyan police spokesman Eric Kiraithe told The Times: "We know quite a bit about her now. She has had three identities in the past and that [Samantha Lewthwaite] is one possible identity."

Kenyan police have been working with British police over the operation and have sent a large team to Nairobi to help with the investigation, the newspaper reported.

Lewthwaite, 28, a convert to Islam who called her husband's actions on July 7, 2005, "abhorrent," is suspected of being part of a cell directed by terrorist group al-Shabab, according to The Times.

Lewthwaite's family say they have not had any contact with her in years, the newspaper reported.

Police are also searching for another British suspect, Habib Ghani of London, according to the Times.
