A thug who caused the death of three teens in a horror car crash threatened to “slit the throats” of police officers after being arrested.
Robbie Gemmell banged his head on the cage of a police van and aimed homophobic abuse at cops who detained him in Haddington, East Lothian.
The officers had been called to reports of a “disturbance” and encountered drunk Gemmell, 25, who targeted them with vile threats.
