Death threat to BBC news chief
Security has been tightened at BBC TV Centre
A telephone death threat has been made against the chief executive of BBC News, Tony Hall, the corporation has confirmed.
But, asked about the threat, a police spokesman said: "It is a line of inquiry being investigated by the Jill Dando investigation team."
It is being stressed that no link has been established, and police say they are still keeping an open mind about the motive for Ms Dando's murder.
A spokesperson for the corporation said: "It is not unusual for there to be threats to presenters or people in the BBC. We obviously take all of them seriously."
The ministry's Website accused the British tabloid press of "lies and manipulations" and called the accusation "criminal" and "racist".
UK Foreign Secretary Robin Cook said British security services had "powers to act" if "anybody from any part of the world may be contemplating action which breaks the law".
"I'm quite sure our security forces have this under review," he said.
The 'E-fit' is being built up following interviews with seven witnesses who saw the man - being treated as the prime suspect in the killing - before and after the shooting.
A Scotland Yard spokeswoman said the picture had not yet been released because police were "still not happy with the quality".
She said: "The release is not imminent. We will let people know as and when."
On Wednesday, Ms Dando's fiancé Alan Farthing appealed for help in finding the killer.
During his first public interview since Ms Dando's death he told the BBC he was devastated.
"I cannot think for one moment what could go through someone's mind when they do such a thing to such a beautiful, caring, well-meaning and as perfect a person as Jill."
He said: "My first emotions now are that whatever happens and whatever arrests are made it does not bring back Jill and that is desperately sad.
Ms Dando was killed by a man who shot her in the head at very close range with a 9mm semi-automatic pistol.
The execution-style manner of the shooting prompted speculation that she might have been the victim of an underworld hitman.
The officer leading the inquiry, Detective Chief Inspector Hamish Campbell, 42, said: "It could either be a stalker or a hitman. However, there are many theories to be explored and nothing will be left untouched."
