The Portimão prowler has been arrested on suspicion of burglary at seven properties in the area.
The police announced that a 51-year-old man has been arrested, presented to court on Saturday and now sits in jail to wait for his trial.
The Public Security Police said they had their eye on the man since last September, suspecting him of a series of break-ins, and applied for an arrest warrant last week, having gathered enough evidence.
On Friday, the police swooped, arrested the suspect and found stolen items at his home, including several Swiss watches, computers, laptops, two tablets, two mobile phones, two cameras and a GPS unit.
