At least one police officer and two suspects were killed Wednesday when a gunbattle erupted during an undercover drug operation in Phoenix, police said.
The shootout left two other officers wounded and two other suspects hospitalized with non life-threatening injuries, said Sgt. Steve Martos, a Phoenix police spokesman.
Two more suspects were detained and being questioned, Martos said. A seventh was being sought.
All three officers were from the Chandler Police Department. One was pronounced dead at St. Joseph's Hospital and Medical Center in Phoenix, authorities said. One of the wounded officers was in critical condition at the same hospital while the other was in stable condition.
The names of the officers were being withheld until their families were notified, authorities said.
Martos told azcentral.com that the Chandler police undercover operation involved about a dozen officers, some of them members of the Chandler department's SWAT team, when shooting erupted inside the home.
Officials did not disclose details of the drug bust or what triggered the shootout.
