A Star Wars-themed event catering to children at the Los Angeles Public Library’s Silver Lake branch on Saturday drew a police response after someone reported a performer dressed as a Stormtrooper as an armed man, authorities said.

The incident unfolded around noon at the library, 2411 Glendale Blvd., a Los Angeles Police Department sergeant said.

Officers responded to a report of a person with a gun and were directed to a performer wearing the costume of the evil warriors from the Star Wars series. The performer carried a large prop gun as part of the costume.

After briefly detaining the Stormtrooper, officers determined the weapon was, in fact, a prop and posed no threat.

The library was hosting its “Star Wars Reads” event, designed to encourage kids to read with the help of the popular science fiction characters.
