DALLAS -- Police said Thursday they have arrested a 15-year-old male suspect for a sexual assault that occurred in Deep Ellum on Sept. 18 after a DNA sample from the teen was a match for the case.

The assault occurred in 3300 block of Elm Street at about 3 a.m. on Sunday, Sept. 18, when the victim was approached by two people. One was armed with a weapon and both sexually assaulted her.

Police sent out a person-of-interest bulletin last month with surveillance footage of the alleged suspect that led to several tips. A search warrant was issued for the juvenile suspect's DNA, then the sample was submitted to the Southwestern Institute of Forensic Sciences.

On Wednesday, detectives were notified that the DNA taken from a sexual assault kit was a match for the 15-year-old.

Police arrested the teen on a charge of aggravated sexual assault, and he is in custody at Henry Wade Juvenile Justice Center. His identity has not been released because he is a minor.

However, the second person of interest in the footage sent out by Dallas police has not been identified, and they are still asking for the public's help to do so. If you have any information regarding the identity of the people pictured above, contact Dallas police.
