A 17-year-old has been arrested after malicious tweets were sent to Olympic diver Tom Daley.
Dorest Police said the teenager was held at a guesthouse in Weymouth hours after 18-year-old Daley received the messages on social networking site Twitter.
A police spokeswoman said: "A 17-year-old man was arrested by Dorest Police officers in the early hours this morning at a guesthouse in the Weymouth area on suspicion of malicious communications.
"He is currently helping police with their enquiries."
Daley and his Team GB diving partner Pete Waterfield missed out on a London 2012 Olympic medal after finishing in fourth place in the men's synchronised 10m platform final on Monday.
After the event, Daley tweeted: "#gutted so sorry everyone but we tried our best and we can't afford to miss a dive at this standard... bring on individual!"
Shortly afterwards, he hit out a Twitter user who accused him of letting down his father, who died in 2011 from brain cancer.
Daley retweeted a message from @Rileyy_69 which said: "You let your dad down i hope you know that."
The diver responded by tweeting: "After giving it my all... you get idiots sending me this..."
Speaking before the Olympics, Daley, from Plymouth in Devon, said his father "gave me all the inspiration that I've needed".
He told the BBC: "Winning a medal would make all the struggles that I've had worthwhile.
"It's been a dream since a very young age to compete at an Olympics.
"I'm doing it for myself and my dad. It was both our dreams from a very young age.
"I always wanted to do it and dad was so supportive of everything.
"It would make it extra special to do it for him."
