Mihail Harabagiu graduated in 1993 from the Police High School in Kiev, Ukraine, and started his career as an inspector at the Police Commissariat in Causeni District. Within the next eight years he advanced to the seat of the commander of the Police Commissariat in the Chisinau Municipality.

In 2007, Mr. Harabagiu took over the leadership in the Civilian Protection and Emergencies Service of the Ministry of Home Affairs; it later was reformed into the General Inspectorate for Emergencies (IGSU). In July 2019, he was under an internal probe for providing the Democratic Party with tents to help its supporters block a number of governmental institutions during 8-14 June. It was a period when the Democratic Party refused to cede the power to a new coalition and tried to boycott transition to a new government.
