A former star of Donald Trump's (search) TV hit "The Apprentice" is accusing workers at a tow truck company of attacking her and her fiance, but the firm's owner says they are lying.

Katrina Campins (search), a 24-year-old Miami real estate agent, and fiance Ben Moss plan to sue soon over the fracas that took place Sunday after they discovered their car had been towed, lawyer Stuart Grossman said Tuesday. Campins suffered a broken nose, swollen eye, leg scrapes, while Moss needed stitches for a split lip, he said.

But Donnie Seay, whose family owns Seay Towing (search), told police the couple attacked him and others.

Police were called following the melee inside the Seay office but they could not immediately unravel conflicting accounts.

"It's still an active case," North Miami Beach police spokesman Sgt. Warren Hardison said. Seay, Campins and Moss were listed as victims in the report, he said.

Campins and Moss had parked their Acura at a shopping mall in Sunny Isles Beach on Sunday afternoon. They went across the street to the Trump International Sonesta Beach Resort (search), where they plan to marry in August.

After a tour of the hotel and lunch, they saw the car was missing. The couple approached Donnie Seay, who was in the parking lot, Grossman said.

Grossman said the driver used "unprintable" insults at Campins, who was fired by Trump on his reality TV show this year.

Seay told WFOR-TV that Campins "started going crazy" and "slapped me in my face."

Campins and Moss then took a cab to the Seay office. Grossman said Moss was punched as he reached for his wallet, and "at least 10 or 12" people joined in the fight. Campins was knocked down and punched during the fracas, Grossman said.

The couple ran to the cab "looking like a bloody mess" and were treated at Parkway Regional Medical Center, Grossman said.

Seay, who said Moss took a swing at one of his brothers upon entering the office, told the television station that the couple was to blame.
