US policeman on Charlottesville terror: 'Hahahaha love this'

Two separate investigations have been launched after a pair of US police officers were allegedly caught mocking a high-profile terror attack on Charlottesville, Virginia over the weekend.

The fatal incident, which saw a car crash into a group of counter-protesters at a white nationalist rally, left 32-year-old Heather Heyer dead and 19 others injured.

Law enforcement already found themselves under fire for not doing enough to prevent violence from occurring at the rally - but now, two officers from have been found to have made light of the incident online.

Conrad Lariviere, a policeman in Springfield, Massachusetts, reportedly left a comment on a post about the attack, saying: "Hahahaha love this, maybe people shouldn't block roads."

He is alleged to have also attacked another Facebook user who criticised his comment by calling them an "ignorant brat [that] lives in a fantasy land with the rest of America while I deal with the real danger".

His police department has been made aware of the comment, and Officer Lariviere has been reassigned while the investigation is undertaken

Meanwhile, Officer Morris Rinehardt of Kentucky has been placed on administrative leave pending a separate investigation into a meme he shared on Facebook.

The meme is said to have been a photo of the damaged vehicle used to plough into crowds in Charlottesville, with the caption "When you were born a Challenger but identify as a Ram," referring to two different makes of Dodge vehicles.

He is also reported to have continued a joke started by another meme on Facebook that was making light of the damage done to the car.
