The Polk County Sheriff's Office is searching for a large swan sculpture that was stolen from a Lakeland cold storage facility last weekend, possibly by a naked man.The Sheriff's Office released video surveillance that officers believe sheds light on the heist. It shows the naked man, whom deputies identified as Ronald Thompson, walking into the Lakeland Cold Storage at 4100 Frontage Road S during the early morning hours of May 19.In one video, the man is seen carrying a bucket in front of his genitals as he approaches the storage facility. A second video snippet a short while later then shows a pickup driving away.Deputies say Thompson stole the 2015 F-150 King Ranch, which they say contained the 5-foot checkered swan. The truck was later located in Hillsborough County. Deputies also found Thompson and arrested him, though so far only on a charge of grand theft motor vehicle.The swan, worth $25,000, is still missing.The Sheriff's Office asks anyone with information on the swan to call (863)298-6200.
