Police say a man has been arrested in the apparently random stabbing of a security guard at a Seattle branch of the Bank of America.

The guard's wounds are described as non-life-threatening.

Police say the attacker had inquired about opening an account Tuesday morning. He told the teller he would return later to complete the paperwork. As he walked out, he stabbed the guard twice in the abdomen without warning.

The 30-year-old guard was taken to Harborview Medical Center.

Police say a man was arrested in the case Tuesday afternoon in the south Seattle suburb of Federal Way. Detective Renee Witt says the man was booked into the King County Jail for investigation of assault.
