Several people have been arrested over this week's deadly attackson Kenya's coast including suspected ringleaders, the local police chief has said.
David Kimaiyo also said that someone had been arrested for using social media to say that Somali Islamist group al-Shabab was behind the attacks.
Some 60 people were killed in two days of violence in Mpeketoni, near Lamu.
President Uhuru Kenyatta has denied al-Shabab's claim to be behind the raids and has blamed local political groups.
"We have arrested several suspects in connection to Mpeketoni incident including the owner and driver of one the vehicles used by attackers," Mr Kimaiyo said on Twitter.
"Also in police custody is a suspect who was operating social media accounts purportedly used by al-Shabab to claim responsibility."
