Tonga Police said the devices will help frontline officers detect and remove more drunk drivers and maintain safety on roads.
Police Commissioner Shane McLennan received the devices from Shelly Wallace of the World Health Organisation at the Tonga Police Headquarters in Longolongo.
The handover of the new devices was possible through an Alcohol Control Support Programme that Tonga Police, WHO, and MoH have jointly spearheaded over the past two years.
The breathalyzer devices will support frontline police officers as they enforce relevant laws in place for alcohol misuse, which include targeting to detect and remove drink drivers as to maintain safety on roads.
WHO supported a week-long training by Daniel Lewis, from the manufacturing company, Remote Control Global (Australia), on the use and maintenance of these devices last month.
