Serbia-Croatia border arrests over radioactive material found in car

3 Croatian nationals have been arrested in Serbia after radioactive material was discovered in their car, Serbian officials say. They were about to enter Croatia on Saturday when scanners detected a “serious amount” of radiation. A subsequent search of an Audi car revealed the head of a radioactive lightning rod in the spare tyre slot of the boot, Serbian customs said. Such rods were widely used in the past, but are now largely being dismantled.
