(Cover) - EN Showbiz - Daniel Radcliffe says "reaching out for help" is the bravest thing a person can do.

The actor appealed to sexual minority teenagers in a new clip for The Trevor project, which offers support to gay, lesbian and bisexual youths.

The charitable organisation also aims to help teens with transgender issues and those struggling to come to terms with their sexuality.

The project's main aim is suicide prevention and to create safe, inclusive spaces at home and in schools.

"I'm Daniel Radcliffe, and I believe that reaching out for help is the bravest thing a person can do," Radcliffe says in the public service announcement. "If you are struggling and need support, call the Trevor Lifeline It's free and confidential, and trained counsellors are there to listen 24/7 without judgment."

The Harry Potter star has been involved with the organisation since 2009 and was awarded the project's Hero Award for his efforts.

He previously called his work for The Trevor Project as "one of the most important, if not the most important, thing that I'm associated with".

The 22-year-old added in a statement that his work has taught him the importance of being a non-judgemental, open-minded friend and supporter.

"When we let someone know that we accept them for who they are and that we are safe to talk to, we can help save lives," he said. "It's as simple as that." (C) Cover Media
