LAWRENCE, Kan. (AP) -- The Douglas County prosecutor will decide whether to file charges against a man who was detained after approaching a Lawrence bank while wearing a bulletproof vest under his shirt.

The Lawrence Journal-World (http://bit.ly/VEOS7o ) reports employees at a Bank of America branch called police Tuesday after spotting the man acting suspiciously. The man had been at the bank previously and had conflicts with employees.

Officers detained the man and seized a firearm from his vehicle. Police said the weapon might have been illegal for the man to possess because of an earlier, involuntary commitment for mental health reasons.

The man was not booked into jail. Police spokesman Sgt. Trent McKinley says his information has been forwarded to the Douglas County prosecutor for review.
