Traffickers flee on foot on A2 and leave behind 81.5 litres of "laughing gas"
A collision between a car and a lorry on the A2, at kilometre 25.6, in the Palmela area, resulted in the seizure of 81.5 litres of nitrous oxide and 600 doses of hashish, according to Correio da Manhã. The occupants of the light vehicle fled on foot before any authorities arrived at the scene.
The accident occurred around 00:30 on Sunday. No one was injured, but the car was immobilised after the impact. According to the GNR's National Traffic Unit, the occupants of the light vehicle "abandoned the location, leaving the vehicle" before the heavy vehicle driver exited the cab or the military police arrived. To escape, they crossed the motorway and jumped over ditches and barbed-wire fencing.
The hasty flight revealed the reason. Inside the car, 28 containers of nitrous oxide were found, totalling 81.5 litres of the product commonly referred to as "laughing gas" — usually commercialised in nightclubs and private parties for the effects of euphoria and relaxation it produces. The vehicle also contained approximately 300 grams of hashish, distributed in 600 doses.
The GNR acknowledges that the occupants, whose exact number has not yet been possible to determine, were heading towards entertainment establishments in Setúbal or in the Algarve to traffic the product that same night.
Both the drugs and the vehicle were seized. The vehicle was removed to a closed park and was preserved for forensic investigation proceedings. The facts were communicated to the Department of Investigation and Criminal Action (DIAP) in Setúbal. The suspects remain at large and continue to be sought.
