Lagos, Nigeria (CNN) — Nigerian authorities arrested 10 people believed to be gay men under a bill signed this week that bans same-sex marriages, rights groups said.
Police detained men in various states and have dozens of pending arrests based on perceived sexual orientation, according to Amnesty International.
“Reports that the police in one state are apparently drawing up lists of members of the lesbian, gay, bisexual, transgender and intersex community to target are extremely worrying,” said Makmid Kamara, a researcher for the rights group.
In Bauchi state, the rights group said police placed “a list of suspected gay people” under surveillance. The group said police arrested the men in Anambra, Enugu, Imo and Oyo states.
CNN attempts to reach Nigerian police spokesman Frank Mba were unsuccessful.
