Shocked residents filmed an electronic display on a MetroLink vehicle reading “Viva Fidel y Raúl,” which means “Long live Fidel and Raúl.”

The apparent praise for the Castro regime in Cuba was captured on video by Dayán Ramírez as he drove down NW 8th and 49th Streets.

Ramírez said he couldn’t believe what he saw.

“It caught my attention because I saw it from far away,” he said. “I said, ‘Could that be it? No, it can’t be.'”

He asked his wife to film the van and then posted the video on social media. The video shows the glowing message on the van’s passenger side windshield.

Local resident Idael Díaz went a step further and contacted the Miami-Dade County Department of Transportation and Public Works (DPTW) to complain.

“My first thought was that the bus driver had decided to leave this message,” Díaz said.

In a statement, Miami-Dade Mayor Daniella Levine Cava confirmed that the sign was “hacked by outside parties.”

“We are deeply concerned about this incident and strongly condemn the message displayed. DTPW is now working with the third-party service provider to implement additional safeguards that will strengthen the security of their systems and ensure this does not happen again,” said Levine Cava.

MetroLink, a new transportation option in Miami-Dade County, connects residents in areas with limited transportation options to major destinations such as the airport, Tri-Rail and Miami Beach.

“I am extremely offended, and I am not someone who is easily offended,” Díaz said. “But to give you an example … it would never be allowed to put up a sign saying ‘Long live Hitler.'”

“I don’t think it’s a joke in bad taste either, because it goes beyond that. It’s no longer a joke because it mocks too many people,” Ramírez said.

It was not immediately clear how many other county-operated vehicles might be affected.
