LOS ANGELES (Reuters) - Los Angeles prosecutors on Tuesday filed criminal charges against the Southern California Gas company over a huge methane leak near the city sparked by an underground pipeline rupture that has forced thousands of residents from their homes since October.

The four misdemeanor charges accuse SoCalGas, a division of San Diego-based Sempra Energy, of failing to report the release of hazardous materials and discharging air contaminants.
