Hernando County sheriff's deputies arrested Arthur K. Malm III, 33, Wednesday on three counts each of sexual battery and lewd and lascivious conduct with a child younger than 12.
According to a report, Malm, whose address is listed as Kings RV Park in Pasco, lived at two Hernando County addresses between October and December 2007.
On three occasions, authorities said, he intentionally touched the victim in the genital area while lying in bed with her.
In April, Malm was arrested in Spring Hill on charges of aggravated battery. He remain in Hernando County Jail on Thursday with no bail.
Third suspect arrested in home invasion case
Authorities arrested a third person Wednesday in connection with a May home invasion in which burglars held two young children with guns to their heads.
Lamont "Montana" Gaynor, 20, of Brooksville, was accused of grabbing an 18-month-old girl and holding her at gunpoint, according to a Pasco County Sheriff's Office report.
Gaynor and two other suspects, 22-year-old Devin Lamm and 19-year-old Nicholas Bernhardt, then forced the residents of the home into a bedroom, the report said.
No one was hurt, and the suspects fled with $100 in cash. A witness picked Gaynor's picture out of a group of photos, the report said.
Gaynor was charged with home invasion robbery with a weapon, aggravated assault with intent to commit a felony and false imprisonment.
He is being held at the Land O'Lakes jail in lieu of $60,000 bail.
