Two robbers leaving a south side Milwaukee jewellery store with cash and gems didn't get far with the loot.
Police said a group of robbers met the two as they walked out and robbed them.
Police said a fight broke out in the street before the groups got in vehicles and a chase ensued.
Officers pulled over both vehicles and arrested four people, including the original two robbers.
But the money and jewels had gone.
