JACKSONVILLE, FL -- Police are looking for two men suspected of exposing themselves to young children at bus stops on Jacksonville's Westside and Northside.

Police say one of the suspects is an older white man who may be driving a green minivan with the back dented in. Reports about this man exposing himself started coming in to the Jacksonville Sheriff's Office in early August. They have received more than a dozen reports.

The other suspect is described as being a light skinned African-American man driving a red Toyota truck. At least three reports have come in on him since early November.

Tammy Halstead's seven-year-old daughter, Brianna, told her something she couldn't believe.

"He was naked and waved at us," said Brianna.

"He came over to that corner (Burns Street and Kingsbury), got out of his car naked, and waved at the kids with his private parts," said Halstead.

She says it happened before her kids caught the bus Tuesday morning. Halstead says she can't believe this suspect has been doing this since August.

She says she worries about what could come next.

"He could just grab them and put them in his car and drive off," said Halstead.

Halstead's daughters aren't the only ones who saw what happened.

"He came out butt-naked and and told us to come over to him but we didn't," said seven-year-old Jailayah Thomas.

First Coast News spoke with the principal of Ramona Elementary School, where these girls go to school.

She says she is working with transportation to make sure busses arrive for the kids on time. She also sent a letter home to the parents explaining the situation.

Police say they need your help in finding these men.
