LOS ANGELES (CBS) — An injury crash on the southbound San Diego (405) Freeway, just west of Sunset Boulevard, forced the closure of four lanes early Wednesday morning.

The crash, which left a car in flames, occurred just after 5 a.m. and shut down the Number 1 and 2 lanes in both directions, the California Highway Patrol said.

A SigAlert was issued, but all lanes were reopened around 6:30 a.m., the CHP said.

It was unclear how the accident occurred or if anyone was injured.
