Police in Britain said on Sunday they were investigating a death threat against Tony Hall, the director-general of the BBC, made on the day he dropped celebrity TV presenter Jeremy Clarkson from the Top Gear motoring show.
Mr. Hall's decision not to renew Mr. Clarkson's contract because of what the BBC said was Mr. Clarkson's unprovoked physical and verbal attack on his producer, generated global headlines and angered many of Mr. Clarkson's fans.
London's Metropolitan Police Service said in a statement it was looking into "an allegation of threats to kill," against Mr. Hall, which was reported on March 25.
"The threat was made by email," the police said. "Enquiries continue to establish from where the email was sent, although the content of the message suggests from outside the U.K."
No arrests had been made, it said. The police did not say if there was a connection between the death threats and the Clarkson case.
