Business Owner Chases, Runs Over Robbery Suspects In Hummer - Two Suspects In Critical Condition
A business owner in Phoenix, Arizona took matters into his own hands after a group of men robbed his business, according to a Local 6 News report.
Police say three armed suspects walked into the Mr. Insurance building in Phoenix and demanded money. A fourth suspect was in the getaway car, according to the report.
Investigators said after the suspects left with the store's money, the co-owner jumped into his Hummer and chased after the suspects.
Police said that the man, identified only as Peter, followed the suspects through a neighborhood and eventually caught up with them. He then rolled his Hummer over their car.
Two of the suspects were taken to the hospital in critical condition.
The two other suspects managed to get away but police later caught them as well.
It is not known if Peter will face charges.
