UPDATE: SIOUX CITY WOMAN CHARGED IN BANK ROBBERY

A SIOUX CITY WOMAN HAS BEEN ARRESTED AND CHARGED WITH THREATENING TO USE A BOMB IN THE ROBBERY OF A SIOUX FALLS BANK.

AUTHORITIES SAY 39 YEAR OLD MICHELLE BOCK ENTERED A FIRST PREMIER BANK BRANCH IN SIOUX FALLS ON TUESDAY, CLAIMED SHE HAD A BOMB AND DEMANDED MONEY. SHE FLED THE BANK WITH 14-THOUSAND DOLLARS CASH.

WHEN SIOUX CITY POLICE SAW SURVEILANCE PICTURES OF THE ROBBERY, INVESTIGATORS IMMEDIATELY RECOGNIZED THE SUSPECT AND BEGAN EFFORTS TO LOCATE HER.

BOCK EVENTUALLY CAME INTO SIOUX CITY POLICE HEADQUARTERS AND TURNED HERSELF IN ON WEDNESDAY NIGHT. SHE WAS ARRESTED ON A FEDERAL WARRANT FROM THE FBI AND TRANSPORTED BACK TO SIOUX FALLS.

BOCK TOLD INVESTIGATORS THAT TWO MEN KIDNAPPED HER, STRAPPED A BOMB TO HER CHEST, AND FORCED HER TO ROB THE BANK.

SHE TOLD POLICE THE MEN THEN TOOK THE MONEY, BUT INVESTIGATORS SAY SHE DEPOSITED NEARLY THREE THOUSAND DOLLARS IN HER PERSONAL BANK ACCOUNT THREE HOURS AFTER THE ROBBERY. SHE DIDN'T REPORT HER KIDNAPPING UNTIL NINE HOURS LATER.

SIOUX FALLS POLICE ARE INVESTIGATING WHETHER BOCK ACTUALLY HAD A BOMB. THEY SAY SHE DID NOT DISPLAY ONE IN THE ROBBERY.

BOCK WILL APPEAR IN COURT IN SOUTH DAKOTA NEXT WEDNESDAY
