Dunwoody and Sandy Springs police are challenging each other to see which department can donate the most blood.
They hope their efforts will inspire the community to also donate.
LIFESouth is sponsoring the event to help raise awareness in local communities about the vital need for regular blood donations.
The challenge between the departments runs until Nov. 7. Officers can donate blood at the LIFESouth facility located at 4891 Ashford-Dunwoody Road in Dunwoody.
The winning department will be selected based on the percentage of officers who participate in the challenge.
Donors from the winning department will be entered into a drawing to win a Blu-ray disc player.
