FUKUSHIMA (Kyodo) Four highway repair workers were killed Tuesday morning and another was slightly injured when a truck ran into them on the Joban Expressway in Iwaki, Fukushima Prefecture, police said.

Trucker Hideto Shibanuma, 42, was arrested over the 10 a.m. accident, they said.

Shibanuma drove into the left-hand lane, which was closed to traffic so it could be repaved, the police said. The right lane was open.

Shibanuma, a resident of Kasama, Ibaraki Prefecture, was on his way back to Ibaraki after delivering packages to Koriyama, Fukushima Prefecture. The repaving work involved around 30 workers.
