A Fulton County Jail detention officer was one of two people injured Tuesday in a predawn wreck in northwest Atlanta.

Fulton sheriff’s spokeswoman Tracy Flanagan said the three-car crash happened just before 7 a.m. on Northside Drive at Kennedy Street.

Firefighters used the “jaws of life” to extricate the detention officer from the vehicle, Flanagan told The Atlanta Journal-Constitution.

Atlanta police spokeswoman Kim Jones said the driver of a southbound Chevrolet Impala drifted into the northbound lanes, striking two vehicles, including the one driven by the officer.

The officer, who was driving her personal vehicle, was alert and conscious when taken to Grady Memorial Hospital for treatment of leg injuries, police said. Her name was not released.

Jones said a passenger in the Impala was taken to Grady in critical condition.

The detention officer was the fourth metro Atlanta law enforcement officer hurt Tuesday in predawn traffic incidents.

Two Gainesville police officers reportedly sustained minor injuries when they were struck by a woman fleeing a routine traffic stop about 4:30 a.m. in Hall County. The officers shot and wounded the woman, who was then taken into custody, police said.

Gainesville police Cpl. Kevin Holbrook said the officers sustained minor injuries. The officer’s names and the suspect’s identity and condition were not available.

Meanwhile, an East Point police officer was injured in a wreck before 5:30 a.m. at Irene Kidd Parkway and Martin Street in East Point.

The East Point officer’s name and condition were not available.
