LOS ANGELES (CNS) - A break in a water main flooded several streets in the Vermont-Slauson area of south Los Angeles early today and led to a large sinkhole.

The break was reported sometime before 3 a.m. near 69th Street and Budlong Avenue, and utility crews were sent to handle the problem.

The break occurred in an 8-inch cast-iron main, and 48 customers were affected, according to the Los Angeles Department of Water and Power.

Budlong Avenue was closed between 68th and 70th streets while crews worked to repair the main, which could take until 4 p.m., the LADWP reported.

Several blocks of the neighborhood were flooded by the break, and a large sinkhole appeared after a few hours, CBS2 reported.

The cause of the break was not immediately known.
