Police are investigating an apparently random attack on a woman in Queens.

Investigators are looking for 28-year-old Richard Springer, who also goes by the nickname "Kwasi".

They say he walked up to the 69-year-old victim and sucker punched her just after 8 a.m. Saturday on Sutphin Boulevard near 108th Avenue in Jamaica.

The woman fell to the ground and suffered a serious head injury.

She is now recovering at the hospital.
