Atlanta police arrested a 19-year-old accused of tackling his victims then robbing them at knifepoint.

Quinlan Pinkins remained in the Fulton County Jail on Monday on armed robbery, aggravated assault and possession of a knife during the commission of a felony charges, according to online jail records.

He was arrested Friday, a week after the Sept. 26 armed robberies in the Candler Park area.

According to a police report, a woman was walking along Clifton Street when she noticed a man matching Pinkins’ description was following her. She began running and Pinkins chased her and tackled her, police said.

Pinkins “threw her down to the ground and began smashing her head on the ground as he choked her,” according to the police report. Police said he then pulled out a steak knife, held it to her head, demanded she unlock and reset her iPhone 6 and give it to him.

Police said Pinkins ran off in an unknown direction with the phone.

The woman waived down a car and the man inside gave her a ride to her home, where she called the police.

That same day, police were called to the 1400 block of McLendon Avenue where a man said he was walking home when Pinkins tackled him, placed a knife to the victim’s left eye and demanded his phone, according to a police report. Pinkins left the scene in a dark colored sedan once he got the cellphone.

Atlanta police said the similarities in the crimes and description of the suspect led to Pinkins’ arrest.
