Four staff at a Detroit tax office have been wounded in a shooting after a dispute over a refund cheque.
Police said the alleged gunman had been arrested and a woman involved in the dispute had turned herself in.
The shooting was reported yesterday afternoon local time at Tax City Tax Service on Detroit's east side.
Deputy police chief Rodney Johnson said the shooting happened after a woman became upset because her tax refund was not yet ready.
She scuffled with a security guard and the man with her pulled out a gun and started shooting.
The security guard was wounded, along with three other employees.
