A woman was knocked out when a drone struck her in the head during the pride parade in Seattle last Sunday, officials said.

The 25-year-old woman was standing in the parade route when she was hit by the 18 square inch drone, according to the city's website.

An off-duty firefighter helped treat the woman, whose boyfriend caught her when she fell, at the scene, the statement said.

The extent of her injuries from the drone, which weighed about 2 pounds and was estimated to cost $1,200, was not immediately known.

Police were looking to speak to an unshaven man in his 20s wearing sunglasses a baseball cap and cut-off pants. The information was based on photographs provided by the victim's friends.

According to the city, he also had a tattoo of a woman.
