Gardaí from Blackrock were called to investigate a suspect package delivered to Microsoft offices in Dublin this morning.
Employees at Microsoft in Sandyford Industrial Estate were evacuated at around 11.30 a.m when a suspicious package alerted staff to a possible anthrax scare.
Part of the building was temporarily sealed by gardaí and the Army to prevent any further possible contamination.
The package has been sent to a laboratory for tests.
