Police said two packages they investigated Monday morning that resulted in road closings and a lockdown at the downtown Rock Hill office of the U.S. Postal Service were found to contain car seats.
The post office was closed and evacuated around 11 a.m. as police investigated what they described as “a suspicious package incident.”
Black Street and Main Street in the vicinity of the post office on South Wilson Street also were closed, Rock Hill police said.
Police said two unmarked cardboard boxes were left outside the post office. The boxes are about three feet tall and had no shipping labels, police said.

A police robot was used to inspect the boxes, police said, and a bomb squad officer took and examined an X-ray of the boxes. The officer also opened the boxes.
Police reported around noon that both boxes contained car seats.
The Rock Hill postmaster discovered the boxes Monday morning and called police.
