It was one of two hoax calls reported Sunday.
“In the first instance, a call was made to GCHQ which resulted in the disclosure of a mobile phone number for the Director. The mobile number provided is never used for calls involving classified information,” a government spokeswoman said in a statement.
GCHQ is the acronym for the Government Communications Headquarters, a British intelligence agency.
“In the second instance, a hoax caller claiming to be the GCHQ director was connected to the Prime Minister. The Prime Minister ended the call when it became clear it was a hoax. In neither instance was sensitive information disclosed,” the spokeswoman said.
Following the two incidents, a notice went out to all departments to be on alert for the possibility of more fake calls, according to CNN.
