Norwegian police have issued an international search request for Rinson Jose, a Norwegian-Indian man linked to the sale of pagers to the Iran-backed Hezbollah terror group that exploded last week, they said on Thursday.

Jose, 39, disappeared while on a work trip to the US last week. He is a founder of a Bulgarian company that was reportedly part of the pager supply chain.

Asked what they were doing to find Jose, police said in an email to Reuters: “Yesterday, September 25, the Oslo police district received a missing person report in connection with the pager case.”
