The suspects -- identified as Subhanna Beyah, 25; Johnnina Miller, 25; Keshia Clark, 27; and Ryan Elkins, 23 -- have allegedly drugged and stolen items from at least four men, CNN reported Friday.
Broward County Sheriff's Office spokeswoman Dani Moschella said it's possible other victims "haven't come forward because they're embarrassed."
"We anticipate identifying other suspects and other victims," she said.
Scott Rosen, 54, told CNN he met two of the suspects at a Fort Lauderdale bar and invited them to his home, where one of them distracted him while the other made him a drink that knocked him out.
"I got drugged," Rosen said.
Rosen said he woke up to find the women gone and more than $250,000 worth of his personal items had been stolen, including his handguns, diamonds and the Rolex watch he was wearing when he brought the women to his home.
"It could have been worse," he noted. "They could have shot me with my own handgun."
The sheriff's department has issued arrest warrants for the women on charges of one count of grand theft each.
"We really want to get these women off the street ... because they're drugging their victims, presumably," Moschella said. "We don't know how long it will be before they end up killing somebody accidentally."
