Mysterious red substance appears along Intracoastal Waterway in West Palm Beach

WEST PALM BEACH, Fla. — The U.S. Coast Guard is investigating a mysterious red substance floating along the Intracoastal Waterway in West Palm Beach on Monday, leaving many in the community looking for answers.

Early Monday morning, aerial video from WPTV Chopper 5 captured the scene on North Flagler along the Intracoastal Waterway.

Around 8:30 a.m., a group of women headed to yoga looked out their condo window and also saw the scene.

"We saw the spill out there, so we went down, and it smelled a little bit like oil," Cathy Boaz said.
