The boy, 17, accused Daley of letting down his late father by missing out on a medal.

Dorset Police has confirmed that it has arrested a boy at a guest house in Weymouth.

“A 17-year-old man was arrested by Dorset Police officers in the early hours this morning at a guesthouse in the Weymouth area on suspicion of malicious communications,” a police
spokesman said.

Daley, 18, and his partner Pete Waterfield, 31, finished fourth yesterday in the men’s
synchronised 10m platform diving event at London 2012.

Twitter user Rileyy69 tweeted, “You let your dad down I hope you know that.” Daley responded by tweeting: “After giving it my all... you get idiots sending me this.”

Daley’s father Rob died last year from brain cancer.

The boy made a series of insulting comments about Daly, including a claim that he would
drown the superstar teenager.

It is believed this tweet resulted in his arrest.

Speaking before the Olympics, Daley revealed about his father who had given him all the
inspiration that he required.

When news of the insensitive tweet spread, Rileyy69 attempted to apologise.

He tweeted: “@TomDaley1994 I’m sorry mate I just wanted you to win cause its the Olympics
I’m just annoyed we didn’t win I’m sorry tom accept my apology,”

He later added: “please I don’t want to be hated I’m just sorry you didn’t win I was rooting
for you pal to do Britain all proud just so upset.”

Dorset Police later confirmed they were investigating the incident.

Daley will compete in the individual event on August 11.
