A 79-year-old man was entering his apartment when the robber approached him from behind and put a knife at his throat.

Four days later on Thursday, September 16, at 1:20 a.m. he allegedly pushed a 68-year-old man to the ground as he was walking near Grand Avenue and West 190th Street.
Once on the ground, the robber took the victim's wallet and ran off northbound on Evergreen Avenue toward East 172nd Street. The victim suffered bruising to his face.

On Wednesday, September 22 at 5:10 p.m., the robber was inside an apartment building on Cruger Avenue and Pelham Parkway South when he victimized 90-year-old John Valenti as he walked inside.
Valenti was approached from and the suspect took his cellphone and wallet containing $150 in cash without the victim knowing. The elderly man was not hurt.
"I didn't know what the hell was going on until he took the money out and I realized he had taken my money, I ran after him, as you can see I can't run really fast," Valenti said.
Valenti said he now takes a different route while walking in his neighborhood. He was born and raised in New York and isn't too fazed by the crime.
"He was just after the money, I'm glad he just took it and left me alone," Valenti said.
The robber is described as a man in his 20s, with a medium complexion and medium build. He was last seen wearing a red New York Yankees baseball cap, a white polo shirt, black pants, a white surgical mask, and dark-colored New Balance sneakers.
Anyone with information in regard to this incident is asked to call the NYPD's Crime Stoppers Hotline at 1-800-577-TIPS (8477) or for Spanish, 1-888-57-PISTA (74782).
