The driver of a minivan that rammed into a truck last week in central Thailand, resulting in the deaths of five passengers, including four Japanese tourists, has been charged, police said.

Two charges — reckless driving causing death, and reckless driving causing damage to others' property — have been lodged against the van driver, Charun Aksonsri, 52, the police said Thursday.

He was at the wheel of the van that slammed into the rear of a large truck at around 4 p.m. Nov. 8 in Ayutthaya, killing four Japanese tourists and their Thai tour guide.

The four Japanese tourists — two men and two women — and their guide died instantly, while the driver was seriously injured.

He is still in the hospital but has acknowledged the charges, the police said. They expect to forward the case to prosecutors within a month.
