Employees and customers were briefly evacuated from the U.S. Bank building at 900 Massachusetts St. about 2 p.m. Monday after a man walked in with a box and said he had a bomb, said Sgt. Trent McKinley, a Lawrence Police Department spokesman.

Witnesses told police the man entered the bank a few minutes before 2 p.m. and climbed over a divider into the bank staff area, McKinley said. When confronted by employees, the man said he had a bomb and threw the box on the floor nearby.

Police arrived minutes later and arrested Craig Allen Bertholf, 62, Lawrence. Officers determined there was no bomb or any other danger, and the box contained only some clothing, McKinley said. Employees returned to the building, and the bank was open again by 2:15 p.m.

Bertholf was booked into Douglas County Jail on suspicion of criminal threat. Bond has not yet been set.
