MINNEAPOLIS - Police say the release of surveillance photos led directly to the arrest ofa 32-year-old man in connection with a violent sexual assault in late June.

DeMarcus Nasson Chaney is charged with first degree sexual assault for the alleged attack, which took place in a south Minneapolis alley early the morning of June 24.

Officers were dispatched to the area of Garfield Avenue South and 22nd Street West around 2:40 a.m. on a complaint of a sexual assault at gunpoint. The victim told investigators that she was walking home from Mortimer's Bar when an African American male approached her from the front, tried to make small talk, then forced her into an alley and pointed a gun at her head.

The victim says her attacker said he'd killer her if she screamed, then pulled off her pants, raped her, and stole her phone. She was taken to Hennepin County Medical Center where fluid samples were recovered.

Police trackedthe victim'scell phone to a man who told them he had purchased it from two individuals outside of the World of Wireless store at Lyndale Avenue South and Lake Street. Investigators recovered surveillance still frames of the two men and released them through the media. A probation officer and a correctional officer both called police and identified one of the men as DeMarcus Chaney.

A DNA sample from the rape victim matched one on file for Chaney, who had previously been in prison. On Wednesday, July 30, The Minneapolis Police Department's Violent Criminal Apprehension Team arrested Chaney.
