Briton held in Kenya over mall massacre

Kenyan police are questioning a British passport holder stopped at Nairobi's international airport over the mall massacre, Sky News has reported.

The man, who was heading for London, has been held since earlier this week after he aroused suspicions at Jomo Kenyatta Airport because he had facial bruising.

Witnesses told how interrogators swooped after the man - wearing dark glasses - rushed to amend the display on his laptop upon arrest.

A Kenyan journalist described him as "jittery" and unable to speak English fluently.

His passport shows he was born in Somalia and, according to Sky News, he received UK citizenship two years ago.

Although he has a base in east London, he has spent time in his country of birth recently and told Kenyan police he got his bruises from fighting there.

Sky's Special Correspondent Alex Crawford said: "The Kenyans believe he has links with al Shabaab and he has a lot of questions to answer.

"They want to know what he was doing in Somalia and whether he knew the mall attackers."

Crawford said Kenya also wants to know whether he has knowledge of the other 200 Britons who have returned to the UK after time inside Somalia with al Shabaab.
