The two detainees -- a man and a woman -- were arrested and their car was seized, while police were searching for the driver of a second car in which the narcotic was found.
The wanted man sped through a police blockade and abandoned his vehicle a short distance away, and fled on foot in the cover of the dark. A search of the car turned up the hashish in one-kilo packages stashed in travel satchels.
The man and women were arrested in another car serving as a look-out for the trafficker.
The detainees will be taken before a public prosecutor.
