A Brevard County postal worker is under arrest -- accused of dealing drugs out of her mail truck.

Rockledge police say 47-year-old Tonya Wheeler was caught during a drug transaction by a postal inspector at the Rockledge Post Office on Murrell Road Wednesday.

Detectives say Wheeler was selling prescription pills to 41-year-old Sean Garriel, who worked as a mail sorter at the facility.

During a search of Wheeler's assigned mail truck, officers found narcotics in her lunch box, drugs she didn't have a prescription for.

They are checking to see if she's involved in ongoing drug-dealing activity.

Wheeler is being held on an 80,000 bond for trafficking oxycodone and hydrocodone pills.

Garriel is out of jail after posting a $2,000 bond on drug-possession charges.
