Dozens of law enforcement officials were called to Pacific Beach Saturday to investigate a suspicious briefcase left behind near a coffee shop.
By 2 p.m., however, authorities determined the briefcase was harmless.
The investigation into the possible suspicious device began around 11:30 a.m. in the 600-block of Diamond Street, near Mission Boulevard and Ocean Boulevard.
Bomb Squad officials were called to the scene to investigate. Police set up a perimeter for hours until the briefcase was deemed harmless.
During the investigation police advised nearby residents to stay indoors and away from windows. Police also advised guests at the Diamond Head Inn to evacuate as a precaution.
A large law enforcement presence remained in the area throughout the investigation.
