Westchester County police say a woman was robbed Friday afternoon at knifepoint in Yonkers’ Tibbetts Brook Park.

They say the woman called 911 around 1 p.m. about two men riding a moped who took her phone.

The woman told police the moped then took off heading south on the South County Trailway away from the park.

Westchester County police and Yonkers police have canvassed the area, but the suspects could not be found.
