Pop star Justin Bieber has been left fuming after his belongings were stolen while he was performing onstage in Washington on Tuesday.

The singer took to his Twitter.com page on Wednesday to tell his 28.8 million followers his computer and camera had been taken during his concert at the Tacoma Dome.

He tweeted, "Sucks when u (you) take personal footage and people don't respect your privacy. Yesterday during the show me and my tour manager Josh had some stuff stolen. Really sucks. People should respect others' property.

"I had a lot of personal footage on that computer and camera and that is what bothers me the most. Lame. No respect."
