Mystery shrouded the torching of nine buses in the Bangladesh capital Dhaka on Thursday, but none was injured, police said.
A police spokesman confirming the incidents said they were looking into the matter and trying to identify those behind the torching of the passenger buses. Late Thursday, several suspects were detained.
The incident also took place as an election to a Dhaka parliamentary seat was underway and ahead of an 18-party opposition alliance headed by the Bangladesh Nationalist Party (BNP) is set to enforce a general strike on Sunday to protest the disappearance of one of their local leaders on Tuesday.
The ruling Awami League, meanwhile staged a demonstration warning the BNP not to engage in such violent politics as they were blamed for killing at least 100 people by setting ablaze a large number of vehicles ahead of the 2014 general elections. The BNP has denied the charges.
According to the Fire Service and Civil Defence Control Room, the buses were first set on fire between 12:00 pm and 2:30 pm and later in the evening in different parts of the crowded city making commuters run for safety along with the panic-stricken passengers. Fire service men rushed and dowsed the fire and no injuries were reported.
The torching incidents took place soon after a bus hit and killed a motorcyclist during an ongoing student protest over their demands. The students denied their involvement in the incidents, media reports said. The driver of the bus has been arrested.
