Since the start of this month, campaigners have also documented the arrest of 21 LGBT+ Cameroonians on charges of practicing homosexuality.
On Feb. 8, two transgender women were arrested in a restaurant in Douala, 12 gay youth were detained in Bertoua town on Feb. 14 and this week, seven gay men were picked up by police in the western town of Bafoussam, LGBT+ activists said.
Alice Nkom, a prominent LGBT+ rights lawyer who is representing the two trans women detained in Douala, said she was "confident" they would be acquitted.
"It is not illegal to be homosexual or transgender. According to our law, it is the act which is the crime. This is a flagrant violation of their human rights," she said, calling for police to investigate the recent murders.
In 2013, Nkom's efforts led to acquittal of two men who were convicted of homosexuality and sentenced to five years in jail for cross-dressing and wearing make-up.
Still, such arrests and prosecutions are common in Cameroon.
Between 2010 and 2014, at least 50 people were convicted for crimes ranging from cross-dressing to a man texting "I love you" to another man, according to CAMFAIDS, an LGBT+ advocacy group.
