Police said a person was robbed at gunpoint in northwest Lincoln on Friday night while trying to sell an Apple laptop computer.
A Lincoln Police Department spokesman said the incident happened in the 300 block of West Charleston Street.
The seller used Facebook Marketplace to facilitate the sale, and after negotiating prices, the buyer flashed a black handgun to the seller before taking off with the laptop, which was valued at $1,000.
Police are investigating the incident and have not made any arrests.
