SHIBUKAWA, Gunma Prefecture--A driver accidentally accelerated and crashed his van 15 meters into a supermarket here on June 10, injuring 14 people, including three children, police said.

Five of the shoppers suffered serious injuries, such as a broken pelvis. The children were 6, 9 and 11 years old. The oldest victim was 78 years old.

Gunma prefectural police arrested Katsuto Yajima, 55, on suspicion of negligent driving resulting in injuries. He has admitted to the allegations.

His van smashed into the main entrance of Torisen Co.’s outlet at 3:55 p.m. and finally stopped after hitting a display shelf, police said.

Yajima, who is unemployed and lives in Shibukawa, said he “mistakenly stepped on the gas pedal instead of the brakes,” according to police.

“I felt numbness on the right side of my body and hit the accelerator,” police quoted Yajima as saying.

A 49-year-old woman whose teeth and toe were broken in the accident said she saw the van hitting a small girl and sending her flying for about 5 meters.

“I don’t ever want to experience such an accident again,” the woman said.
