Apple's headquarters in Cork, Ireland, was evacuated on Monday morning after a number of threatening emails were allegedly received by the tech giant. As a result of the possible danger, about 4,000 employees from three different offices in the area were temporarily evacuated, according to The Irish Independent.

Apple's offices on Lavitts Quay and Hollyhill, as well as the Model Farm Road site, were allegedly evacuated as a safety precaution. After the employees were successfully evacuated, authorities proceeded to search the facilities.

Despite the search, however, a spokesperson from the Garda Síochána said that bomb disposal units from the army have not been deployed to the scene, reports The Register.

"We're assisting in searches with security teams from the facility as a result of a security alert," the spokesperson said.

Authorities were ultimately unable to find any suspicious items or devices within the premises of Apple's offices. The alert, which was issued at about 9 a.m., was finally lifted about midday, with workers being allowed inside the facilities once more, according to The Telegraph.

The Cork site is Apple's base of operations in Europe. Employing about 5,000 staff across its offices in the area, the Cork site also builds iMac computer units.
