Deputies surrounded a home Sunday, after a man armed with a crossbow holed-up inside for more than four hours before ultimately surrendering, officials said.

The incident began just before 10 a.m. Sunday with a report of a fight between a father and son in the 18000 block of Mescal Street, Sgt. Pauline Panis of the Los Angeles County Sheriff’s Information Bureau said.

When deputies arrived, the son — initially described only as a man — retreated into the home and displayed a crossbow to deputies, Panis said.

It was not believed that he had fired the weapon at anyone. In a written statement, sheriff’s officials described the holed-up man as a suspect involved in an assault with a deadly weapon involving a crossbow, though further details of the alleged assault were not available.

Deputies summoned a sheriff’s SWAT team to the home to take over the standoff, officials said.

“The suspect is believed to be the sole occupant in the residence,” sheriff’s officials said in a written statement. “For the safety of the public, surrounding homes in the area have been evacuated.”

After slightly more than four hours, officials persuaded the suspect to exit the home and surrender about 2:05 p.m., deputy Amber Smith of the Sheriff’s Information Bureau said. The crossbow was recovered.

His identity was not immediately available, nor were the charges he was expected to be booked for. Officials at the sheriff’s Walnut-Diamond Bar Station declined to comment, referring all inquiries to the Sheriff’s Information Bureau. No further details were released.
