Police have made an arrested a man in the brutal Wednesday night attack of a beloved homeless man in the Tenderloin.

Arthur Lee Jones of Fairfield was arrested by an SFPD officer on Thursday night around 10:45 p.m. near the same intersection of Larkin and Geary Streets where the attack took place. The officer recognized Jones from the surveillance video that captured the attack and made the arrest. In the video, you can see the suspect approach Robert with a metal pipe or bat and forcefully hit him in the head.

KRON 4's J.R. Stone spoke to Jones in jail and asked him if he was the man who attacked the homeless man named Robert. Stone said, "He sort of smirked, and took a step back, and said he wasn't going answer one way or another, especially not until he saw the video." Jones also said he didn't know Robert.

When asked if Jones looked like the suspect in the video, Stone says his facial features and hair matched, but in person his skin tone looks darker. However, Stone added the caveat that surveillance videos tend to have filters that could alter the color of the footage.

Jones also told the reporter that when he was arrested 10 people told officers he wasn't the attacker, and that three others said he was only telling the police what they wanted to hear. Jones was charged with aggravated assault and attempted murder.

The video shows that the attack was unprovoked. "Before I looked up after lighting a smoke, Robert was hit on the head by a pipe and this guy is almost walking on top of me and I'm not quite sure if what I just saw happened or didn't happen," Justin Cunningham, the person who can be seen smoking a cigarette in the footage, told ABC 7.

Police say that Robert and his attacker may have been involved in a confrontation before the attack. Locals in the Tenderloin described Robert as a nice guy who never caused trouble for anyone.

Robert required 50 stitches to his head and remains hospitalized in critical condition.
