Police have arrested a Kenyan suspected of aiding the gunmen who kidnapped a British tourist and killed her husband, an official said Tuesday.
The suspect is believed to have information about the organizer of Judith Tebbutt's kidnapping and her husband's killing, said Stephen Ikua, the government administrator of Kenya's Lamu West district. He said the organizer was a Kenyan who operates in Somalia and has links to al-Shabab.
The al-Shabab militia group is leading an insurgency against Somalia's weak government and has sworn allegiance to al-Qaida. The group has threatened to attack Kenya on several occasions.
Ikua said he thinks the group may have fled to Somalia with Tebbutt, but he is not aware of any communications with the kidnappers.
He declined to give further details, citing ongoing investigations.
British police officers have also traveled to Kenya to help investigate the murder and kidnapping on a remote island resort.
London's Metropolitan Police said Tuesday that some of its officers were working with Kenyan authorities searching for a British widow abducted after her husband was shot dead at a beach resort on Kiwayu Island near the border with Somalia
David and Judith Tebbutt had arrived at the resort Saturday and were attacked on their first night on the island.
London police said the force had sent a "small team" to Kenya but declined to say how many officers were in the country. It added that Kenyan authorities remain the lead investigators.
