A 32-year-old man was arrested on Monday night after he was found in possession of drugs during a roadside check.
The police said on Tuesday that Paola district police were carrying out road checks in Triq il-Perit Dom Mintoff in Paola, when they stopped a Volkswagen Up for inspection.
They noted that the driver and the passenger, a 34-year-old Italian, were acting suspiciously.
Officers searched the car and found what they suspected was cocaine in the passenger door, as well as dangling with the car keys. They also found a bag containing cash.
The man was first taken to the Paola police station and later to the lock-up at the police headquarters in Florinaa.
Police investigations are continuing.
