U.K. authorities say one of the suspects in last week's deadly attack on a British soldier was arrested in Kenya in 2010.
Officials say Michael Adebolajo was getting ready to train and fight with the al Qaeda linked terrorist group al-Shabab when he was taken into custody.
"Kenya's government arrested Michael Olemindis Ndemolajo. We handed him to British security agents in Kenya, and he seems to have found his way to London and mutated to Michael Adebolajo," government spokesman Muthui Kariuki said.
"The Kenyan government cannot be held responsible for what happened to him after we handed him to British authorities," he said.
This new information leads some to ask what U.K. officials knew about the suspects in the apparent terror attack.
"We can confirm a British national was arrested in Kenya in 2010. The Foreign and Commonwealth Office provided consular assistance as normal for British nationals," a British Foreign Office spokeswoman said in a brief statement.
She added that she had no information about what had happened to Adebolajo then.
So far, a total of nine people have been arrested in relation to British soldier's murder.
Meanwhile, the British government is setting up a terrorism task force to tackle extremists.
The panel will consider whether the government needs new powers to clamp down on religious leaders who promote extremist messages and target recruits in jails, schools and mosques.
