Investigators said the man told the females to get into his van but they refused.
Sheriff Michael Adkinson Jr. said Hulgan was arrested about 2:18 p.m. at an apartment complex in Seagrove and charged with a felony count of lewd and lascivious behavior and a misdemeanor count of indecent exposure.
"Our deputies apprehended the suspect within minutes of receiving the call," Adkinson said. "They should be commended for their rapid response and quick thinking."
The South Florida Sun Sentinel said Hulgan works as general manager of WLJR, a radio station operated by the Briarwood Presbyterian Church in Birmingham, Ala.
