SIOUX CITY, Iowa (AP) -

A Sioux City man faces up to 20 years in federal prison after pleading guilty to bank robbery.

Federal prosecutors say 27-year-old Johnnie Hawkins, of Sioux City, entered his plea Wednesday in federal court in Sioux City.

Prosecutors say Hawkins brandished a stolen .40-caliber semi-automatic handgun on Nov. 10 when he robbed the Heritage Bank in Sioux City. Prosecutors say Hawkins had confronted and threatened an employee while she was opening the bank. He got away with nearly $6,000.

Hawkins' sentencing date hasn't been set.
