At approximately 6:30 PM, the woman was walking with a friend along a footpath on North Lake Drive, when a man on a bike approached from behind, a witness and an LCSW coordinator said.
The man then allegedly knocked one of the women to the ground and proceeded to grab her before fleeing the area, the coordinator said.
Police and LCSW were called.
The suspect was described as a Hispanic male, wearing all black.
LCSW says they are stepping up surveillance in the area.
