Manama — Joint operation by Saudi and Bahraini authorities led to the arrest of five more people suspected of involvement in smuggling RDX explosives into Saudi Arabia, said Bahraini Chief of Public Security Maj. Gen. Tariq Al-Hassan here on Saturday. He commended the alertness of the Saudi authorities which led to the detection of explosives and the arrest of culprits. He said that as part of the joint investigation into the attempt to smuggle 'RDX' into Bahrain, a team of representatives from various authorities of the Interior Ministry was formed to work in coordination with their Saudi counterparts. Several houses were searched after warrants were obtained from the Public Prosecution. This led to the confiscation of material suspected to be explosives, mobile phones, laptops, portable hard disks, cameras, Iranian mobile phone chips and Saudi, Jordanian and Iranian currencies. Al-Hassan said investigations will continue until all suspects are identified and arrested. He said the items confiscated by Saudi officials yesterday were similar to the material that Bahrain police seized on a boat coming from Iraq on Dec. 28, 2013, and through the King Fahad causeway on March 15, 2015. Suspects in both of those cases were arrested.
