An 18-year-old suspect is facing robbery charges for allegedly stealing a pair of Nike sneakers at gunpoint from a woman selling them on Facebook, according to Denver police.

The shoe seller, Gabrielle Aludo, agreed to meet a person who identified himself as "Isaiah Guaps" on Facebook in hopes of selling the pair of Nike tennis shoes, according to documents from the Denver District Attorney's office.

Aludo reportedly asked $180 for the sneakers but the suspect, Leroy Isaiah Bolden (using the alias Isaiah Guaps), allegedly proposed to pay $20 more if she would agree to meet him on a street corner in Denver, the court documents report.

When the two met downtown more than one month ago, the suspect reportedly pointed a black semi-automatic pistol at the woman's face and ran off with the sneakers down an alley, according to police. After Aludo notified police, she did some detective work on Facebook and was able to help officials identify the suspect, according to the court papers.

When ABC News attempted to search Isaiah Guaps on Facebook, no account linked to that name could be found. ABC's Denver affiliate KMGH reports that police found 56 pairs of Nike shoes when they searched Bolden's home.

Bolden is currently in custody and faces charges of aggravated robbery and menacing. He is scheduled to appear in court on Jan 15.

Aludo and Bolden's attorney could not immediately be reached for comment.
