Tucson authorities hope to find violent robbers before they strike again.
Arizona authorities are searching for two men involved in a violent home invasion.
The robbery carried out at a Tucson home on October 28 was captured by the home owner's security cameras.
Pima County Sheriff's Deputies released graphic video of the attack.
The video shows three suspects attack the victims at gunpoint as they force their way into the home.
One of the suspects has been taken into custody.
Deputies are still looking for the other two, and say they have information indicating they already have more robberies planned.
