AFP apologises over Seven raid error

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."
