A British couple and a Maltese man were arrested on Tuesday after a search yielded packets of cannabis and one ecstasy pill, the police said.
The Drug Squad was alerted to possible drug trafficking taking place in an apartment in Qawra. They set up surveillance and a man leaving the apartment was searched and found carrying a packet of cannabis that he had just bought.
The apartment was searched and a British couple aged 41 and 37 were arrested after 74 packets of cannabis and the ecstasy pill were found.
They are expected to be arraigned in the coming days.
Magistrate Francesco Depasquale is leading an inquiry.
