The Police Service of Northern Ireland said they were investigating the circumstances of his "sudden death" in his home town on Friday.
PSNI officers have also issued advice to young people about the need to be careful when using the internet.
Mid-Ulster district commander Supt Mike Baird warned them not to share personal information online with strangers.
He described the boy's death as "tragic".
"Officers have spoken to pupils at a school in the area and offered advice regarding safe internet use and any type of virtual interaction including social media sites, chatrooms and through interactive games," Supt Baird said.
"If anyone has experienced anything of a similar nature or has received any inappropriate images or links, it is important that they contact police or tell a trusted adult."
