A 20-year-old Sacramento man was arrested Wednesday morning after an alert citizen noticed a suspicious person prowling near a residence in the 2100 block of Rheem Drive.
The citizen called police and reported that the male subject entered the rear yard of a residence as soon as the residents left, Sgt. Pat Walsh said.
The man, later identified as Roman Phillips, allegedly approached the front doors of several other houses and tried to open doors to parked vehicles in driveways.
Police were given a detailed description of the man and where he was traveling from the citizen.
Officers surrounded the area and allegedly located Phillips behind a business.
Police reports said Phillips provided false identifying information to officers and had just hidden an expensive bicycle in shrubbery.
Phillips was arrested on suspicion of prowling and possession of narcotics.
Walsh said the investigation is continuing as there might be additional victims of theft or burglary.
"In this situation, the suspect would not have been identified or captured without the help from this alert community member," Walsh said in a statement released Wednesday. "The Pleasanton Police Department reminds citizens to immediately call the police when they see suspicious behavior or people."
