OKLAHOMA CITY (AP) - The chief of Oklahoma's Capitol patrol says security for the inauguration of state officials has been enhanced following the weekend shooting of a congresswoman in Arizona.

Highway Patrol Capt. Pete Norwood says more than 50 troopers will be on hand for Monday's inauguration on the south steps of the state Capitol.

Norwood says the number of tactical officers assigned to the Capitol was doubled following Saturday's shooting of a Arizona Congresswoman Gabrielle Giffords. Six people were killed and at least a dozen were injured in that attack.

Norwood said security already was tight for the inauguration, but some additional officers were added in the wake of the shooting.

Uniformed officers were present on every floor of the state Capitol Monday morning, and bomb-sniffing dogs roamed the grounds.
