Pacific Gas & Electric is warning customers to watch for an impersonator who has threatened and demanded money from at least two customers.

PG&E said customers should always verify an employee's identification.

Recently, two customers in Kern County have had someone come to their door claiming to be a PG&E employee. The impersonator then threatens to shut off the electricity and gas unless they collect money.

In one case, the impersonator allegedly did shut off the power.

PG&E gave no timetable for when these incidents occurred, saying only that customers alerted them of the incident.

PG&E said it does not collect money door-to-door, and that all employees will have company identification.

PG&E asked said if anyone comes to the door and you suspect the person is an impersonator, you should call the police and then call PG&E at 1-800-743-5000 and notify them of the incident.

Any customer with questions about the impersonator can also call the number listed above.
