Four people have been shot at a tax preparation office on Detroit's east side.
Police say one man has been arrested and they are seeking at least one woman in the Friday afternoon shooting which followed a fight over money inside the business.
The shooting was reported shortly after 3:30 p.m.
Chief James Craig said the fight started because a "payment wasn't ready" and "there was a physical altercation" with a security guard.
The security guard was wounded, as were three other employees in the office. One victim was in critical condition, while the other three were listed in serious condition.
