Four chain snatching incidents in one month have some Bronx residents on high alert.

Police officials say that the initial incident happened on Aug. 10 at 1047 White Plains Road, just before noon.

They say a 20-year-old woman was walking toward IHOP when she was approached by man wearing a hood. He proceeded to grab the victim's neck and snatched her necklace. Surveillance video shows him speeding off in a dark blue minivan, traveling southbound on Watson Avenue.

Just two days later, a second attack occurred nearby at 1350 Morrison Ave. in Soundview just before 10 a.m. A 71-year-old woman was approached by another man wearing a hood. In a struggle to pull the woman's jewelry from her neck, the man shoved her into a fence, causing her to sustain a scratch on her arm.

Some residents say they've stunned.

"It's either they're really brave or really crazy because everyone knows each other around here," Hassan added.

The violence continued on Aug. 14, when a 44-year-old woman was attacked at 965 East 172nd St. Police tell News 12 that a group of men proceeded to snatch the victim's jewelry from her neck and then returned to what seemed to be the same dark blue minivan from the previous incident.

“I don't like what's going on,” said resident Mark Crawford. “Even though you snatch a chain, you can really hurt somebody in the process.”

The most recent attack occurred on Aug. 18, near Lincoln Avenue and Bruckner Boulevard. Suspects crept up behind a 68-year-old man just before noon and ripped his chain from his neck, before taking off in the dark blue minivan.

All four victims - three women and one man - escaped serious injury, but the emotional toll remains.

"You don't want to come out, you don't want to wear your jewelry," Crawford said. "You want to buy something and keep it. Not have somebody take it because they feel like it."

Police tell News 12 that they are urging anyone with information to come forward if they recognize any of the individuals involved, and to contact the NYPD Crime Stoppers Hotline at 1-800-577-TIPS or submit a tip online at the Crime Stoppers website.
