The Region : Bombing of Norwalk Firm Investigated

Los Angeles County sheriff’s bomb squad officers investigating the explosion of a pipe bomb on the roof of a Norwalk computer assembly firm discovered a second, undetonated, device and removed it. Deputy Sam Jones said the explosion blew an 18-inch hole in the roof of the Songlin International Corp. in the 11800 block of East Firestone Boulevard over the weekend. Arson and explosives detail officers were called when employees discovered the damage upon arriving for work. The second pipe bomb was taken away and detonated. Song Yeh, manager of the company, said he did not know who might want to damage the plant.
