An FBI agent who accidentally shot a bystander after his gun went off while dancing in a Denver night club has been charged with second-degree assault.

The agent, who has been named in the US as Chase Bishop, could also face further charges pending the results of an alcohol blood test.

The Denver District Attorney's Office said Bishop, 29, turned himself in on Tuesday morning after an arrest warrant was issued and has since been booked into jail.

District Attorney Beth McCann said: “We are filing this charge now rather than waiting until the BAC report is received, which we understand could take another week, because sufficient evidence has been presented to file it.

“If an additional charge needs to be filed after further evidence is received, we can file those charges then.”
