LITTLE ROCK, Ark. (AP) - A former police chief in Oklahoma and Texas has been sworn in as police chief in Arkansas' largest city.

Former Norman chief Keith Humphrey was sworn in Monday as head of the Little Rock Police Department.

Humphrey comes to Little Rock after spending the past seven years as head of the Norman police department. He spent the prior three years as police chief of Lancaster, Texas, after working as an officer in both the Fort Worth and Arlington police departments.

Humphrey takes over at a time the department faces a civil rights lawsuit over "no-knock" warrants, an age and racial discrimination lawsuit by four officers and criticism over a fatal officer-involved shooting in February.

Humphrey has vowed to end the no-knock policy and to meet with police and the community.
