The Saigon South Traffic Police Team (Ho Chi Minh City Police Department of Road and Railway Traffic Police) was present at the scene to check and handle. Seeing the functional forces, the “monsters” increased the gas and ran in many directions. After the pursuit, the functional forces controlled one subject, but then this subject ran away, leaving the “modified” vehicle that did not meet many technical safety requirements.
