The Federal Aviation Administration has opened an investigation after a DJI Inspire 1 crashed and injured a nearly one-year-old girl in Pasadena, California earlier this month.

The crash of the 6.4 pound drone took place during a September 12 movie screening of The Princess Bride at City Hall, according to the Pasadena Star News. The child sustained a quarter-inch cut on her head and a bump on the forehead—she was seen at Huntington Memorial Hospital and released.

On Monday, Ian Gregor, an FAA spokesman for the Pacific Division, told Ars in a statement that the inquiry had begun.

"The FAA is concerned with the growing number of reports about unsafe operations and is stepping up both its education and enforcement efforts," he said. "Anyone who flies carelessly or recklessly can face fines from $1,000 to $25,000, depending on the seriousness of the violation. The FAA has initiated more than 20 enforcement cases, settled five cases in which operators paid fines, and has proposed penalties in at least five other cases."

The day before this fateful flight, a University of Kentucky law student was charged with wanton endangerment after crashing his drone at Commonwealth Stadium before the Kentucky Wildcats' matchup with Louisiana-Lafayette.
