This police officer wears a blue hat, which features a gold badge or shield in the middle.
The gender of this emoji is not specified, but is commonly shown as a man.
Police Officer was approved as part of Unicode 6.0 in 2010 and added to Emoji 1.0 in 2015.
The Police Officer emoji supports skin tone modifiers. A yellow (or other non-human) skin tone should be shown by default, unless an emoji modifier is applied.
Platforms without support for emoji modifiers display a missing symbol character (box with a cross, alien, or question mark in it) next to any modified emoji.
