Fans boo Bieber for late show start

Teenage superstar Justin Bieber left fans angry and disappointed, with some booing, after he arrived on stage nearly two hours late for a sell-out UK concert.

The singer did not begin his performance until 10.30pm - long after many of his school-age fans would normally have been in bed.

His late showing at London's O2 Arena was not explained, according to fans at the show, and many blasted the 19-year-old Canadian with messages on Twitter.

Some complained they were stranded after the late finish and a number of others had to miss the gig altogether in order to catch the last train home from London.

Father Wayne Parsonage said he ended up missing the show to ensure he could get home, and wrote on Twitter: "Disgusting. Waste of my time and money... never again."

Tracey Wilson, from Hoddesdon in Hertfordshire, took her teenage daughter, who has school today, to the concert.

The pair were left stranded after missing their train home and instead had to be collected by her husband.

She told BBC Radio 5 live the support acts overran by around 20 minutes to 8.50pm, finally followed by Bieber an hour and a half later.

She said: "There was no apology to say why or 'I'm really sorry' or to say something's happened. It's disgusting.

"It got to about 9.30 and they were starting to boo - you'd think someone would have come on then."

Another tweet complained: "Justin Bieber needs to understand he has fans that are really young. He can't come on stage like 1 hour and 45 mins late on a school night!"

It was the first of Bieber's four nights at the London venue.

At 11.36pm, the official account for the 02 tweeted: "Justin Bieber is now on stage and apologises for the lateness of his show."

It later added: "Sorry to all the Justin Bieber fans for the lateness of his show tonight. The Tube will still be running when the show finishes."

An official account for Transport for London warned the Jubilee line would be busy following the concert, with the last train at 12.15am.

The world-wide Believe tour has already stopped in Manchester, Liverpool, Birmingham and Nottingham.

Bieber has been photographed on a string of nights out since he arrived in the UK for his shows, including one appearance in which he was seen outside topless in chilly weather.
