Police yesterday said that two or more people could be involved in Thursday's minivan gas explosion at a parking lot next to the Taipei Railway Station and letters threatening a bomb attacks mailed to two local TV stations.
"Our preliminary investigation showed a few interesting findings -- that the suspect or suspects may not possess experience in producing bombs, and that we may be looking for more than one suspect," said Feng Tung-san (
Feng said that the police believe that the suspect or suspects don't know how to make a bomb because no explosives or detonators were discovered at the scene on Thursday, even though the letters sent to TV stations said there would be "bomb explosions."
"Common gasoline was used in the van explosion," Feng said.
"It is quite possible that two or more suspects were working together," he added.
Two local TV stations -- TTV and TVBS -- reported receiving bomb threat letters at around noon on Thursday -- almost precisely the moment when a minivan exploded in the parking lot adjacent to the train station.
In the letters, the suspect or suspects warned that at least four bombs would explode before yesterday's legislative elections took place. It also stated that Taipei Railway Station and the Taipei 101 building would be targeted in the attacks.
According to the CIB, officers are currently investigating evidence gathered at the explosion site and questioning members of Taichung's criminal underworld after they discovered that the minivan was stolen from a dealership in Taichung County.
