Metro Police have arrested a 26-year-old black man who sexually assaulted a woman at gunpoint

The black suspect, Shawn Brock, is being held without bail at the Clark County Detention Center on counts of burglary, robbery, sexual assault with a deadly weapon, first-degree kidnapping with a deadly weapon and robbery with a deadly weapon, according to arrest reports. The burglary and robbery counts stem from an unrelated purse-snatching incident that happened several hours after the sexual assault. Police said that the sexual assault occurred shortly after midnight on June 18, 2012 when Brock followed a 19-year-old woman leaving Mini Mart, 3455 N. Nellis Blvd. The victim told detectives she rebuffed the black man’s advances when she was shopping at the convenience store. As she walked to her nearby apartment complex, the woman noticed the black man following her in a sport-utility vehicle. The African-American suspect then cornered her inside the complex and pointed a handgun at her while demanding money. When the victim said that she didn’t have any money, he ordered her behind a Dumpster, where he sexually assaulted her. After the attack, the woman flagged down a nearby officer and reported the sexual assault. Detectives used surveillance images from Mini Mart to identify the black suspect as Brock. In the process, detectives learned that Brock had been arrested several hours after the sexual assault. Police arrested him after he stole a woman’s purse from her car at a downtown parking garage. When detectives interviewed Brock in jail, he denied the sexual assault — instead saying he paid the victim $40 for sex. Detectives, however, located a handgun at the apartment where Brock was arrested for the purse-snatching. The handgun matched the description of the weapon described by the victim in the sexual assault.
