Arts groups say BT to block access to The Pirate Bay
UK arts pressure groups have called for BT to block access website BitTorrent file sharing, The Pirate Bay.
Music industry trade body the BPI, said it would take legal action if the telecommunications company refused to cooperate.
The movie industry has forced BT to block NewzBin 2, only members that aggregates of illegally copied material.
BT said: "We can confirm that we are in receipt of a letter from BT BIS is considering its response.".
The telecom operator said a warrant would be necessary before the lock could begin.
A source told the BBC that the company was unlikely to fight a long legal battle as it did in the case NewzBin.
"We do not tolerate 'R' Us Counterfeits on the main street - if we want economic growth, we can not accept illegal scam sites or good," said BPI chief executive Geoff Taylor.
Richard Mollet, executive director of the Publishers Association adds: "It is crucial that the creative sector maintains the momentum to make Internet companies to do their part in the fight against illegal sites."
The Motion Picture Association, the independent trade body PACT Campaign and the Creative Coalition also expressed their support.

The Pirate Bay was launched in 2003 by a group of friends in Sweden and quickly became one of the most popular file sharing sites on the web.
Although not hosts files, allows users to search and obtain a copyright content such as movies, games and television programs.
In April 2009, Swedish courts found the four founders of the site guilty of helping people to bypass the controls of the copyright.
They decision was upheld on appeal in 2010, but the site still works.
