The Department of State Service (DSS) said it arrested a man named Jones Abiri who uses the alias General Akotebe Darikoro.
The arrest took place on Thursday in Yenagoa in southern Nigeria, amid “ongoing tactical operations to degrade the capabilities and hideouts of criminal gangs” in the country.
The DSS claimed the militant confessed to attacking pipelines operated by Agip — the Nigerian subsidiary of Italy’s Eni — and Anglo-Dutch oil group Shell.
Several recent attacks, including assaults on pipelines operated by Shell and Agip, have been claimed by a militant group named the Niger Delta Avengers (NDA).
