A church worker at The Church of the Presentation in Stockton says that five bronze plaques were stolen from the outside of a building last week.
Each plaque represents people who donated to the church.
Police released surveillance video of the thief in action and say early last Wednesday morning, a man managed to pry plaques off the wall.
On the video, you only see the man on the bicycle stealing a plaque, but police say there was another suspect there who acted as a lookout.
They say both left the scene on bicycles.
If you have any information about where the stolen plaques may be, contact Stockton Police.
As for the church, a worker tells us they're getting better cameras to help catch future thieves
