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.

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.
