Ian was killed by the suspected kidnappers while three others were released and returned safely after Nigerian authorities negotiated their freedom.
IYC described the incident as unfortunate and highly condemnable, noting that it did not reflect the character of Niger Deltans.
A statement by IYC President, Eric Omare, maintained the death of the Briton was a case of criminality and should be treated as such.
“The people of Niger Delta are peaceful and hospitable as evidence by the centuries of missionaries from foreign countries having peaceful sojourn in the region”, it said.
IYC urged security agencies to bring the perpetrators to justice as soon as possible. “The perpetrators must not be allowed to go unpunished.
“We again call on community and traditional leaders to support security agents to help in fishing out criminals from their communities”, he said.
The group further disclosed that it would soon set up clan and community security structures to work with security agencies in order to make Ijaw communities uncomfortable place for criminals.
