[KHTS] – Santa Clarita Valley Sheriff’s Station deputies responded to a domestic violence call resulting in deputies finding a grenade and conducting an hours-long search Monday night.

Deputies responded to a report of a spousal assault on the 17300 block of Sarita Avenue, in Canyon Country, around 5:30 p.m.

The suspect allegedly hit his girlfriend, who is nine months pregnant, and then apparently fled the scene.

When deputies responded, they had information leading them to believe the suspect might still be on the premises, so an aerial unit was called, as well as a K-9 unit to search for the suspect.

During a search of the house, deputies found what appeared to be a grenade in one of the rooms.

The Sheriff’s Department’s Arson/Explosives Unit was called to the house, while a helicopter assisted deputies who established a perimeter in their efforts to find the suspect.

The grenade was later determined to be a nonworking ordnance.

Sheriff’s Station officials did not release the name of the suspect they’re looking for, who was not found.

The victim was treated on the scene by Los Angeles County Fire Department personnel, and then transported to Henry Mayo Newhall Memorial hospital.

The victim was not seriously hurt, according to officials.

The search lasted several hours, and deputies are still seeking the suspect for questioning about the accusation.
