Miscreants set fire to two parked buses at separate locations along the Dhaka-Aricha highway in Savar late Sunday night.
One of the buses belonged to Itihas Paribahan, while the other was used to transport garment workers.
Jahangir Alam, a senior station officer at Savar Fire Service, confirmed the incidents on Monday morning.
According to the Fire Service, the first incident occurred at Genda bus stand, where a bus used to transport garment workers was parked. Miscreants allegedly set the vehicle on fire and fled the scene. Firefighters later arrived and brought the blaze under control.
In a separate incident, around 4am, a passenger bus operated by Itihas Paribahan caught fire in front of a Tata servicing centre near Baliarpur bus stand along the same highway. Firefighters responded to the scene and extinguished the blaze.
Jahangir Alam said the two incidents involved a worker-transport bus in Genda and an Itihas Paribahan passenger bus in Baliarpur.
He added that preliminary assessments suggested both buses had been deliberately set on fire as acts of sabotage.
