Mac address learned through AP when connected via wired

Odd issue i ran into. There are several pc's hardwired to a switch but for some reason the mac address of those pc's shows up being learned from the ap hanging off of that same switch. The ap uses the same vlan as the switch for access and only has one ip associated with it via the bvi. The bvi ip is in the same subnet as the rest of the small network. There is not a physical loop in the topology either. Also those pc's are not somehow multi-homing with wired and wireless. Any ideas what may cause this behavior?

Figured it out. Turns out the "engineer" that did the consultation for this location used a poe injector to power the AP. This POE injector tied into a hub. The port on the switch that was showing the ap as a cdp neighbor was also tied into the hub on that port. What a ruckus.

Always look closely at the physical topology no matter how much of a rats nest it may be.
