The US Secret Service has suspended a high-ranking supervisor due to knowledge of his "illegal conduct and possible criminal activities".
The suspended Secret Service supervisor, who guards President Obama and performs other highly sensitive tasks, has been denied access to classified documents and restricted areas.
Spokesman Brian Leary said Wednesday that the case was reported to the Secret Service's Office of Professional Responsibility on April 2 and that inspectors have reviewed the report.
Secret Service Director Joseph Clancy was notified the same day.
The Department of Homeland Security's inspector general is investigating the case, Leary said, declining to say more.
Another investigation into the work of the Secret Service is ongoing.
Two high-ranking officials are accused of driving their car through the security barricades of the White House on March 4, allegedly under the influence of alcohol.
