BIG PINE KEY, Fla. -

A Big Pine Key woman who stole towels from the laundry room of a trailer park threatened the owners with a knife when they tried to get them back from her, according to the Monroe County Sheriff's Office.

Robin Grabey, 52, pulled a knife on a man and his friend and said she would stab them after they asked for the towels back, Monroe County Sheriff's Office spokeswoman Becky Herrin said.

Someone in the laundry room said he had seen Grabey take some towels from the dryer, which led the 19-year-old man and his 27-year-old friend to confront her.

A witness said he saw Grabey threaten the men.

Grabey was arrested on a charge of aggravated assault with a deadly weapon.
