The first incident occurred at the Emerald Pointe Apartments on Camino Colegio at 3:01 a.m.

Police said the masked man walked up to the front door of a residence, stood there for a brief moment and then walked away.

The second incident occurred eight minutes later at 3:09 a.m. in the 1300 block of Miramonte Place.

In that incident, the man walked up to the front door of a residence, stood there for a brief moment while grasping the doorbell camera and then walked away.

In both incidents, the individual did not attempt to enter the front doors, did not remove anything and did not appear to be holding any tools or weapons, police said.

The man was wearing a full-faced white mask, was dressed in dark clothing and had a full beard, police said.

Police said the individual's actions were concerning but are not criminal.

Detectives are also investigating an incident that occurred on Sept. 4 at 1:15 a.m. where a man entered a residence in the 1300 block of Middlebrook Way.

When one of the residents woke up and saw the man, the intruder said "Sorry" and walked out of the home.

The suspect in that incident was described as a Hispanic man, 5 feet 7 inches tall and was wearing all black.

Anyone with information on these incidents is asked to call the Rohnert Park Department of Public Safety at (707) 584-2600.
