Dawaun Lewis, 30, was taken into custody Wednesday in the 2100 block of Girard Avenue. He is charged with murder, robbery and related offenses.
Police say Lewis is the man pictured in a surveillance image released by investigators earlier this week.
The victim, 45-year-old Keisha Furlow, was beaten to death in an alleyway on North 24th Street around 2 a.m. Sunday.
Surveillance video obtained as part of the investigation shows a man throwing Furlowto the ground in the alley.
It reveals how the attacker repeatedly struck the mother of four in the head with a brick, before stomping on her face and chest.
Police said Thursday that two bloodied bricks were found at the scene.
Furlow's purse was taken after the beating and recovered a few blocks away, emptied of its contents.
