Police in the northern province of Son La have arrested a man and seized 36,000 pills of illicit drugs after chasing him through a mountainous area.
Vang A Phong, 31, reportedly ran his motorbike into a group of police officers when being stopped at around 11 p.m. on Saturday.
After falling off the motorbike, Phong jumped into a gorge nearby in an attempt to flee.
Three groups of police officers chased after him and managed to catch him after 30 minutes.
Police said the pills weighed more than 3.3 kilograms in total, without confirming the types of drugs.
