The failure of the Los Angeles Sheriff’s Department’s computer-aided dispatch system in its vehicles had left deputies to resort to old methods as they responded to calls.

LOS ANGELES (AP) — The archaic computer dispatch system for the nation’s largest sheriff’s department remained out of commission on Thursday after crashing on New Year’s Eve, forcing deputies to handle all calls by radio, authorities said.

It’s not clear how long it will take to fix the problem, but in the meantime deputies and dispatchers must use radios instead of patrol car computers.

Deputies can once again receive calls for service through their patrol car computers, according to a Friday statement from the department.
