The cause of the seven-fold collision that made the center of Haeundae downtown in Busan a mess was caused by the driver's'hallucinations', according to the police investigation.

The Busan Police Agency announced today (15th) that it is investigating a Porsche driver A (40s) who had a seven-fold crash on charges of drug administration.

Mr. A is known to have confessed to inhaling hemp in a vehicle just before the accident during a police investigation.

Before and after the accident, Mr. A showed abnormal driving behavior in the middle of the city to the extent that it was expressed as a'frenzy running', and crashed several vehicles including motorcycles, causing great damage.

It was also confirmed that two more accidents were made before the 7th crash.
