The Australian Federal Police has been forced to apologise in connection with raids on Seven Network offices.
The AFP raided Channel Seven's inner-Sydney offices this week as part of a proceeds-of-crime investigation.
There was speculation the network had opened its chequebook for a tell-all broadcast interview with convicted drug smuggler Schapelle Corby, who is on parole in Bali.
The AFP accused Seven solicitor Justine Munsie of a crime in documents to the Federal Court to get orders signed to justify the raids.
On Friday, the AFP apologised for that accusation, saying it was "an innocent word-processing error".
"The AFP regrets any hurt, embarrassment or offence which this error has caused," it said in a statement.
"This regrettable error does not invalidate the search warrants, or the order itself."
Attorney-General George Brandis described the incident as a matter for the AFP.
"However, I am concerned about how this appears to have been handled," Mr Brandis said in a statement.
"I will be seeking to establish how this error was apparently made by the AFP."
