A Virginia police officer has been fatally shot on her first day on the job.

Ashley Guindon had only joined Prince William County Police on Friday.

She and two of her fellow officers were shot when they responded to a domestic disturbance in a suburb of Washington, DC.

A suspect is in custody, and the two other officers are being treated for their injuries.

In a statement on Facebook, the police department said, "we ask for everyone’s thoughts and prayers as our department deals with this tragic loss.

"We also ask for continued patience as we learn more about this incident," they added.

Officers from the department and members of the public have been paying tribute to Ashley Gundon:
