The Kauai Police Department is investigating threats made against Mayor Bernard Carvalho Jr. about his decision to veto a bill that would require large farms to disclose the type of pesticides they use on fields and implement buffer zones for spraying.

Police Chief Darryl Perry said Friday that police are focusing on one threat made via social media by an individual believed to be a male. The threat of physically harming the mayor was made shortly after Carvalho announced his decision to veto Bill 2491.

"We take this very seriously," said Perry during a phone interview Friday.
