Police are asking for the public's help to identify a suspect who attacked and punched a 67-year-old man as he was heading into his home in Brooklyn.
Investigators released a photo of the suspect on Saturday.
Francis Ellis was attacked at 1:20 a.m. on April 23 on Herzl Street in the Brownsville neighborhood. He credits his son with stopping the vicious assault.
"If my son didn't come downstairs, I don't know what, he might have killed me," Ellis said.
Ellis said the assailant "came out of nowhere" and started hitting him.
His son Jarrod rushed outside when he heard his father shouting.
"I did what I had to do, to protect my father," he said.
"My son beat him up," Francis Ellis said.
The man then fled.
The motive for the attack is unknown.
Anyone with information about the suspect is asked to call the NYPD Crime Stoppers Hotline at 800-577-TIPS.
