A 14-year-old schoolboy has died just weeks after he made a YouTube video revealing he was gay. Liam, a pupil at Glenrothes High School , Fife, was found dead at a home on Sunday afternoon. Police Scotland today confirmed his death was being treated as “unexplained”.

It is not clear how he died but police are looking at the possibility it is linked to prescriptions drugs in circulation at a number of schools in the area. There is widespread online speculation that Liam may have taken his own life as a result of bullying. In a video, recorded last month, he came out as gay and anticipated ridicule from some classmates.

Heartfelt tributes have been left over social media following news of the teenagers death. Liam’s sister, Chelsea, posted a photograph of the pair together writing: “R.I.P Liam. You were the best and only brother I had I love and miss you so much wish you were still here you meant the world to me. I am so heartbroken without you Liam, dunno what to do anymore. I just wanna be up there with you why did you have to go so soon?”
