Four men believed to be members of a White supremacist gang have been arrested on suspicion of committing two hate crimes last year, police said.
Authorities believe the suspects beat a 23-year-old man at a Phoenix bar in March 2007 and stabbed a 32-year-old man at a Phoenix convenience store in June 2007.
In the first attack, police said the men made "White power" comments and hit the Hispanic victim in the head with a barstool.
In a second attack, police believe as many as nine gang members assaulted and stabbed a Black man at Walgreen's after using racial slurs to verbally abuse him.
The man was hospitalized and needed surgery to repair serious injuries, police said.
Police believe suspected gang member Chad Kerns, 30, of Buckeye, stabbed the man twice in the abdomen and then fled before police arrived at the scene.
Also arrested were Jamie Lyon, 20; Doolin Onion, 20; and Preston Onion, 23 - all Phoenix residents.
The four men face multiple charges, including aggravated assault and leading or participating in a criminal street gang, according to police.
