GLENDALE, Ariz. -- Police in Glendale say they've struck a blow against a street gang responsible for armed robberies, aggravated assaults and one murder.
At a news conference Wednesday afternoon, police announced that they've arrested dozens of people affiliated with the criminal group.
Glendale Police Chief Debora Black say nearly 60 people affiliated with the Grandel gang have been taken into custody so far in the year-long investigation and other arrests are expected.
Nine of these arrests occurred Wednesday while others happened months earlier in the case.
Police say their investigation of the gang began when they examined a February 2010 stabbing death in which a gang member was later convicted of killing a man.
Investigators say the majority of the gang's victims were fellow criminals.
