A British teenager was arrested and released on bail Monday after he tweeted an Olympic diver, the Guardian said.
Great Britain divers Tom Daley and Pete Waterfield placed fourth in the men's 10-meter synchronized diving event after which the 17-year-old tweeted "You let your dad down I hope you know that," the Guardian said.
Daley's father died of brain cancer a year ago and Daley had hoped to win an Olympic medel for him, CBS News said.
Daley replied, calling the tweeter an "idiot" and a slue of obscene messages from the accused tweeter and others followed, CBS News said.
The teen tweeter was issued a harassment warning and is being investigated, the Guardian said.
