Two suspects led police on an hours-long chase through Los Angeles and San Bernardino counties and barricaded themselves in a house, where they remained for hours.

According to the California Highway Patrol, the pursuit started around 12:52 a.m. in Pasadena and nearly an hour later, the suspects stopped at a house in a cul-de-sac in Ontario and barricaded themselves. 

A SWAT team was called in at 4:19 a.m., police said. The scene remained active, but no surrounding residents were evacuated. 

As of 8:50 a.m. Sunday morning, the suspects were still barricaded, authorities said.

By later in the afternoon, it was unclear if the barricade situation had been resolved or if the suspects were taken into custody, though CHP’s Inland Division confirmed to KTLA that as of 4 p.m., there were no units in that area.
