Police have officially arrested a man in connection with blasts at a Jehovah’s Witnesses gathering in Kerala which claimed three lives.

The explosions on Sunday also injured more than 50 people.

A suspect, Dominic Martin, has since been arrested under an anti-terror law.

Martin had earlier posted a video online claiming responsibility for the incident, before surrendering to police.

Kochi city police commissioner A Akbar said, “We are convinced that he committed the crime based on his confession and corroborating pieces of evidence we collected.”
