Authorities are investigating a security breach at a downtown Hartford government building that houses the offices of several state agencies and officials.
State police said a security alarm activated just before 5:15 p.m. Sunday at the State Office Building at 165 Capitol Ave.
Officials from the state Department of Administrative Services said Monday morning that an unauthorized person was found inside the vault area of the basement of the state office building and was placed in custody.
The offices of the Connecticut attorney general, secretary of state and treasurer are among those that operate out of the State Office Building.
