Hertfordshire Police have urged the public to “not approach and dial 999 immediately” if they spot 26-year-old Kyle Clifford.
The man, from Enfield, north London, is wanted in connection with murders of three women who were found fatally injured in a house in Ashlyn Close, Bushey, Hertfordshire, just after 7pm on Tuesday.
In a press conference, the police reaffirmed their calls for the public to aid their efforts in hunting down the suspect.
