SANIBEL ISLAND-Fla.-Sanibel Island Police are offering a 25-thousand dollar reward to help solve a string of beachside burglaries. In the last eight weeks, Police say thieves targeted 15 properties from the 500 block of east gulf drive to the 34-hundred block of west gulf drive. In most of the cases, the victim's left their porches unlocked. Officers plastered warning fliers all over the island to alert tourists. They believe all the burglaries are connected.

Tourist Margaret Aycock said, "The flier was very handy they let us know they care about our safety and we took precautions we made sure was locked."

Police Chief Bill Tomlinson said, "We believe they watch people leave there condos and after they leave their sliding doors open he goes in enters the unit and steals jewelry and cash."

The 25-thousand dollar reward is in addition to the reward for tips that come in through crime stoppers. If you know anything call the Sanibel Police Department.
