Five suspects were on Tuesday arrested over the attack at Widhu Majembeni in Lamu county, which saw six people killed on Monday.
National Police Service spokesperson Bruno Shioso said the suspects are being grilled over the attack which is linked to land disputes.
He added that they are following leads in a bid to establish whether the attack has any connections with the outlawed al Shabaab militia or their sympathisers operating in the area.
“All the suspects are locals and we are talking to them to establish more over the attack,” he said.
Earlier on Tuesday, one person was burnt beyond recognition following an attack at Bobo-Hindi in Lamu county.
The deceased was identified as John Moji.
It comes as more security was deployed in the area to trace more suspects over the latest attacks.
A team of detectives has been sent there to back up with locals to help in the operation.
