Authorities surrounded a home in Whittier Sunday morning after a suspect in an assault with a deadly weapon was believed to have barricaded himself inside.

The hourslong incident began around 2:35 a.m. on the 7900 block of Comstock Avenue in Whittier.

The suspect, an unidentified man, was reported to have barricaded himself inside a home and refused to surrender to Whittier police.

The Los Angeles County Sheriff’s Office responded to the scene with a crisis negotiation team in hopes of convincing the man to surrender.

Surrounding homes were evacuated as the incident progressed, the Sheriff’s Department said.

Residents were urged to avoid the scene while law enforcement was in the area.

By 2:20 p.m., authorities determined that the man was not inside the home and neighbors were allowed to return to their homes.

The scene was cleared after it was determined that the area was safe, LASD said.

Anyone with information about the incident is urged to contact the Whittier Police Department at 562-567-9200. Anonymous tips can also be submitted online at lacrimestoppers.org.
