SLCPD SWAT Team Safely Arrests Aggravated Assault Suspect    


SALT LAKE CITY — A collaborative effort between the Salt Lake City Police Department’s SWAT Team, SLCPD patrol officers, and crisis negotiators resulted in the arrest of a 34-year-old man who refused to come out of his apartment after being involved in an aggravated assault.

This investigation started at 7:35 p.m. on Sunday, July 30, 2023, when SLC911 got a call about a man threatening people with a knife in an apartment near 1740 West 400 North.

The victim safely got out of the home and told officers the suspect, Delmar Castillo, pulled out a knife and threatened to kill them.

There were no reported injuries.

Officers tried contacting Castillo several times but he refused to come out of the house.

Officers continued their attempts to get Castillo to peacefully surrender.

The on-scene incident commander requested the assistance of SLCPD SWAT and Crisis Negotiators. These highly trained teams provide patrol officers with additional resources.

SLCPD’s SWAT Team and Crisis Negotiators continued to try and get Castillo to exit the home, but he refused to talk with them.

After obtaining a court-authorized search warrant, the SWAT team safely took Castillo into custody.

Officers took Castillo to the Salt Lake County Metro Jail and booked him on charges of aggravated assault and obstruction of justice.

One photo from the scene is being released. Media may use the photo with proper credit to the Salt Lake City Police Department.

Charges are only allegations, and every arrested person is presumed innocent unless and until proven guilty beyond a reasonable doubt.

The Salt Lake City Police Department is not the custodian of record for jail booking photos. Utah Code 17-22-30 mostly prohibits the release of jail booking photos. Generally, a jail booking photo can only be released by the custodian of record after a conviction or when law enforcement determines the person is a fugitive or an imminent threat to a person or public safety. In Salt Lake City, the Salt Lake County Sheriff’s Office is the custodian of record for jail booking photos.
