Orlando police are warning online shoppers to urge caution when buying items off Craigslist this holiday season after a woman was held at gunpoint during a transaction.

Police said 30-year-old Christian Roldan arranged to meet the woman to sell gift cards on South Conroy Road.

When the woman got there, officers say Roldan pointed a gun at her and robbed her of $1,800.

Police tracked Roldan down by using his number from the Craigslist ads.
