Seven upset with AFP again over Corby raid

Seven has fired off a letter of complaint to the Australian Federal Police following recent raids on the TV network's offices.

The AFP raided Seven's offices in Sydney last week in relation to the network's intention to conduct a paid interview with convicted drug smuggler Schapelle Corby.

On Tuesday Seven started action in the Federal Court to "review and set aside the decision ... to issue search warrants" and have the material seized by the AFP returned.

In a letter to AFP Commissioner Tony Negus dated February 26, Seven's CEO Tim Worner also demands a "correction and retraction" from the AFP.

The letter says Mr Negus and his deputy Michael Phelan told a Senate estimates committee on Monday night that Seven had told them on February 14 and 17 that it had "no further documents".

This is not true, Worner writes.

"Seven disagrees that you have accurately represented or conveyed Seven's response to the AFP.

"At no time did Seven or its representatives make an unqualified statement to the AFP that Seven had no further documents or words to that effect."

He has asked Mr Negus to stop saying Seven had "no further documents".
