Police said that in one instance, on Jan. 24, the man approached a 70-year-old woman at 76th Street and Glenmore Avenue. After brandishing a knife, stole $100 and $6,300 worth of jewelry.

The chain of violent crimes has spread fear throughout the community, and has many residents worried for the safety of their loved ones.

"I have three children. We've actually experienced robberies here, and we're behind a gated fence," Rivera said.

The robber is still at large. Anyone with information is asked to call Crime Stoppers at 1-800-577-TIPS.
