(AP) Taiwanese pop star Jam Hsiao says he's outraged by an alleged attack in which two autograph-seekers threw a bucket of fecal matter at into his van.
The 26-year-old singer told reporters Tuesday that two motorcyclists approached his van asking for autographs before the attack. He said his driver was hit but he was unharmed.
Hsia said he was outraged by Monday's incident and called on the authorities to find the culprits, saying "I demand an answer."
He said he had no known enemies and did not know who would want to harm him.
Known for his explosive high notes, Hsia rose to Mandarin pop prominence after appearing on a talent show in 2007.
