A man who calls himself “Dolphin Dave” was cited by Hawaii officials Monday who said he was harassing a humpback whale and a pod of dolphins. 

Hawaii’s Division of Conservation and Resources Enforcement received several calls Sunday to report someone harassing wildlife, the Department of Land and Natural Resources said in a statement. Officials were told a man, later identified as 65-year-old David Jiménez of Maui, was seen pursuing an adolescent humpback whale inside Kealakekua Bay State Historical Park on the island of Hawaii. 

DOCARE officers then received a video of Jiménez snorkeling close to an adolescent humpback whale, almost touching the whale’s fin.

When DOCARE officers arrived on shore Monday, officials said they recorded Jiménez leading a group of swimmers chasing a pod of spinner dolphins.
