THE brother of a man killed by a police car said he will not stop protesting until he gets "justice".

Karl Holscher-Ermert was joined by several dozen people outside the headquarters of Sussex Police in Lewes on Saturday.

They were calling for action over the death of Arthur Holscher-Ermert, who was hit by the unmarked police car, a black BMW, on April 30 near Bramber Avenue in Peacehaven.

The 27-year-old had been briefly pursued by a different police car and, as he got out of his Audi and was crossing the road, he was struck by the BMW.

Some protesters shouted expletives at a police officer on the other side of a fence during Saturday's gathering.

Arthur’s older brother Karl is calling for the officers involved in the incident to be suspended pending an inquiry.

He said: “Three weeks on, nobody has been suspended, nobody has been arrested. In a normal scenario, you’d hope that at the very least the officers involved would be suspended while the investigation is carried out.

“Sussex Police have said that Arthur’s death does not meet the required threshold for suspension - that is a disgrace and a slap in the face.”

Karl said his grief has been prolonged unnecessarily as his family and friends have not been able to have a funeral for Arthur.

“We haven’t had the chance to grieve, because we are waiting for his body to be released,” he said.

“The whole thing is being prolonged for no apparent reason.”

Earlier this week, Sussex Police had a private meeting with Karl to offer their “deepest sympathies”.

However, Karl said in that meeting, he was told Arthur’s death "did not meet the required threshold for suspension".

“That is a disgrace and a slap in the face,” he said.

“Why Sussex Police believe they are above the law and don’t have to suspend the people involved, nobody understands.”

Karl said the support he has received from the community has “kept him going”.

He said: “We all stand united, we all stand together and this needs to be sorted sooner rather than later.

In a statement, Sussex Police said: "We were aware of a planned protest which took place outside Sussex Police headquarters at Lewes on Saturday, May 21.

"We understand the strength of feeling following the tragic death of Arthur Holscher-Ermert, and we are providing every assistance to the Independent Office for Police Conduct (IOPC) to allow for a thorough investigation and for the family to receive the answers they need.

"Our thoughts are with Arthur’s family and friends and we would ask the public to allow for the investigation to take its course."
