Bus blast not 'work of terrorists'

SHANGHAI: Shanghai police have ruled out the possibility the May 5 blast on a bus that killed three people and injured 12 others was terrorist-related.

Vice-director of Shanghai public security bureau Chen Jiulong said on Wednesday, "unresolved conflicts" might have been behind the explosion.

The police had offered a 50,000-yuan ($7,500) reward for information about a man killed in the incident.
