Channel Four’s Doug Kriegel will have a story at 6 p.m. tonight on KNBC detailing a series of extortion threats to various asian businesses in the San Gabriel Valley.

Kriegel said he was tipped to the story thanks to a Chinese-speaking member of the KNBC staff who reads the Chinese Daily News. Today’s piece is a follow up to one he ran with on Friday.

“These are Chinese death and extortion threats,” Kreigel said.  “Threats from the Taiwanese Mafia.”
