By Concord Police Department

The Concord Police Department has arrested 24-year-old Daniel Alejandro Acosta-Montiel for a series of sexual battery and false imprisonment incidents that occurred over the past several months.

• The first incident occurred on January 13, 2025, where Acosta-Montiel reportedly followed a woman, grabbed her from behind, and sexually assaulted her.
• A second incident occurred the following night, where Acosta-Montiel allegedly used a stun gun on a female victim and sexually assaulted her.
• Approximately one month later, Acosta-Montiel was identified as the suspect in an incident where he followed a female home and assaulted her in the front yard of her residence in Concord.
• After his arrest, a juvenile female came forward and reported that Acosta-Montiel had sexually assaulted her in October 2024.

Once identified in April 2025, Concord PD Detectives arrested Acosta-Montiel on numerous felony charges, which were subsequently filed by the Contra Costa County District Attorney’s Office.

Acosta-Montiel, born 12/01/2001, is described as a male, 24 years old approximately 4 feet 11 inches tall and approximately 120 pounds.

Given the circumstances of this case, the Concord Police Department believes there may be additional victims. Acosta-Montiel lived in Concord during these incidents, but also had connections to East Contra Costa County.

Anyone with information is urged to contact Special Victims Unit Detective Huffmaster at 925-671-5080 or Concord PD Dispatch at 925-671-3333.

According to the Contra Costa Sheriff’s Department, Acosta-Montiel is being held in the Martinez Detention Facility on no bail, and his next court appearance is on Friday, August 8 in Superior Court in Martinez at 8:30 A.M.
