LGBT Egyptians became the target of a particularly fierce crackdown in 2017, after several Egyptians were arrested for sharing images of a rainbow flag flying at a Mashrou’ Leila concert in Cairo. Though homosexuality is legal in Egypt, LGBT Egyptians are charged with "debauchery and immorality." Fifty seven LGBT Egyptians were arrested by October 2017, with ten of them being sentenced to between one and six years in prison. This crackdown follows similar efforts by Egyptian police to use Grindr, a dating app for gay men, to entrap gay Egyptians. This practice began in 2014 but is still occurring as of 2017.
