FULLERTON, Calif. (AP) — Fullerton's police chief has been placed on leave just a year into his job while authorities investigate his off-duty conduct.

The city manager says David Hendricks and another officer are on paid administrative leave.

The Fullerton Police Officer's Association says the other officer is Capt. Thomas Oliveras, who commands the Operations Division.

The two couldn't immediately be reached for comment and authorities declined to provide further details.

However, Irvine police spokeswoman Kim Mohr says her department is investigating a disturbance involving Hendricks and some emergency medical technicians that occurred Friday night at a Lady Antebellum concert in that city.

Mohr says Hendricks and the others were ordered to leave but there were no injuries or arrests.

Hendricks became Fullerton police chief in July 2017.
