The Ministry of Environment (MoE) patrols seized a potable water tanker transporting diesel on Shamal road.
A patrolling squad handed over the vehicle and the driver to security authorities.
This is the second time the ministry has seized a water tanker carrying diesel from Al Shamal in the recent months.
Last time, the ministry had seized a water tanker carrying diesel after a patrolling squad found it parked near a petrol station in Al Shamal. The driver, however, escaped.
The government recently ordered to set up a committee to fight the growing diesel black market in Qatar.
The panel has been tasked with putting an effective strategy in place to combat the menace.
As a first step, the panel is expected to strengthen rules relating to the distribution of diesel and its monitoring and frame new regulations, if necessary.
