A Yonkers woman has pleaded guilty to attacking a pregnant county worker.

Prosecutors say 30-year-old Melissa Cochrane got into an argument with Department of Social Services case workers.

Officials say she grabbed a pregnant staff member and knocked her to the ground.

The incident happened at a district office on Warburton Avenue on Christmas Eve.

Cochrane pleaded guilty to disorderly conduct last month.

She was sentenced to a year of conditional discharge and must complete community service.

The victim was also granted a protection order.
