NEW YORK (CBSNewYork) — Police are looking for suspects in connection with a violent robbery in the Bronx.

It happened on March 12 in front of an apartment building on College Avenue.

An 18-year-old woman was approached by three unknown individuals who demanded she hand over her cell phone as she tried to get into her building, police said.
