Teen arrested over Twitter abuse of UK diver Tom Daley

(CNN) - British police arrested a teenager suspected of sending an offensive Twitter message to British Olympic diver Tom Daley.

Officers detained a 17-year-old man at a guest house in "the Weymouth area" of the county of Dorset in the early hours of Tuesday morning, they said.

The unnamed teenager is being questioned on "suspicion of malicious communications," a police spokeswoman told CNN.

On Monday, Daley retweeted a message he said he'd received from user "Rileyy_69" shortly after he and his partner Peter Waterfield placed fourth in the men's 10m synchronized dive, failing to win a medal.

"After giving it my all...you get idiot's sending me this...RT @Rileyy_69: @TomDaley1994 you let your dad down i hope you know that," teen diving star Daley tweeted.

Daley's father died in May 2011 after a long battle with brain cancer.

The tweet triggered a stream of support and praise for Daley's efforts, and disgust at rileyy_69's message snowballed into a campaign to have him banned from Twitter.

#GetRileyy_69Banned was trending on Twitter as users urged others to retweet the message. A tweet from @QuotingJokes calling for a ban was retweeted more than 12,000 times overnight.

After a barrage of negative comments, Rileyy_69 posted several apologies on Twitter, claiming he didn't realize that Daley's father had died.

"but mate i didn't know about his dad I've just seen about it on the news they mentioned me," he wrote.

In the early hours of the morning, he managed to tweet "I'm going to the ****** police station now to sort this out I will be back."

His last tweet read: "night everyone and im geniunely sorry for what's happened today just know that im actually a really nice person and I regret what I've said."

Police have 24 hours to question him in custody before deciding whether any charges should be filed.
