PHOENIX - Video note: Viewer discretion is advised.
At around 2 a.m. near 32nd Street and Baseline Road, police say a woman walked into the gas station, hit the employee with a brick then demanded the code for the register.
She's then seen walking out with another woman who had items in her hands.
The clerk received a concussion from the attack and was treated for her injuries. She told police she did not know her attacker and that it was a random act of violence.
"One of the suspects has already been identified and arrested in connection with this incident," police said.
As for the suspect still missing, she's described by police as a black female, between 20 and 30 years old, about 5 feet and 4 inches tall. She was wearing a cheetah-printed hoodie, multi-covered pants, pink shoes, and a black backpack.
