COLLIER COUNTY, Fla.- The search is on for the suspects involved in four home invasions in the past five weeks. The most recent happened in a gated Collier County community, near Osprey Trail. Both Naples Police and Collier County deputies say the robbers used duct tape to tie victims up.

The latest home invasion happened Tuesday night in the Estuary neighborhood. Naples police and Collier County deputies said the suspects are men, and that they entered the home through the back porch.
