A Muslim has been jailed for threatening to kill police officersReuters

A racist Muslim who threatened to blow up police officers and cut off one's penis has been jailed for almost three years.

Haroon Rashid was chased by police officers after he punched a man in the face with a homemade kuckle duster.

Officers took off in pursuit of the 31-year-old following the road rage incident in July last year. When they caught up with Rashid he launched into a tirade, saying: "I am going to cut off your dick, you f***ing white infidels," Snaresbrook Crown Court heard.

He also threatened to "blow them up".

Ten days later, Rashid then also threatened a member of staff at an an unemployment advice centre with knuckledusters, the court heard.
