A “Back the Blue” mural was painted outside of a Tampa police station over the weekend.

On Monday, Tampa police officers were greeted with a message of support.

According to Fox 13, volunteers gathered over the weekend to paint a “Back the Blue” mural in front of the Tampa Police Department’s headquarters, even though they did not get the permit approved for the mural to be painted.

The project was headed by a group called “Community Patriots,” who said they got permission to paint the message. However, Tampa Mayor Jane Castor said the permit had not been approved before the mural was painted.

“Any tribute to honor their service is welcome,” Mayor Jane Castor said. “It’s unfortunate they didn’t see the permitting process through so that our community could participate in showing their appreciation for the brave men and women that service our residence every day.”

The mural features blue, white and black colors. The mural also features a heart, stars and the U. S. flag.
