The shadow home secretary said that urgent work must be done to rebuild trust between police and the community after the Independent Police Complaints Commission (IPCC) published preliminary results from its investigation.
The watchdog said on Wednesday that an object removed from the 20-year-old’s throat by paramedics “did not contain a controlled substance”.
Unverified footage on social media appeared to show at least one policeman attempting to restrain Charles on the floor of a shop in east London before he died later in hospital on July 22.
Abbott hinted that the trust in police forces had broken down within ethnic communities.
Miss Abbott said: “The IPCC’s update, coupled with the release of a Metropolitan Police report highlighting a disproportionate use of force against black and minority ethnic people, will no doubt cause deep concern and upset.
“Urgent work must be done to rebuild trust and links between the police and the community.”
Charles’s death sparked violent clashes with police in Hackney on Friday as demonstrators hurled bottles and fireworks at officers.
Miss Abbott said the riots were “wrong” and she joined with Charles’s family in calling for peace.
“There must be justice for Rashan and his family, but there is absolutely no cause for any more violence,” the Hackney North and Stoke Newington Labour MP said.
The IPCC said its investigation into the circumstances of Charles’s death following contact with police in Hackney is “ongoing and making good progress”.
The watchdog said: “Our independent investigation is thoroughly examining all aspects of police interaction with Rashan prior to his death and has already undertaken a large number of investigative actions.”
Last week, the IPCC said the evidence it had seen so far suggested that Charles was detained by a Metropolitan Policeman who had followed him on foot into a shop on Kingsland Road after an earlier attempted vehicle stop.
The officer restrained Charles, with the help of a member of the public, and he was handcuffed.
After he was detained, attempts were made to remove an object from his mouth or throat.
His condition deteriorated, and the officer called for a police medic who provided assistance prior to the arrival of paramedics, according to the IPCC.
On Tuesday figures released for the first time showed Metropolitan Police used “force” at a rate of around once every 10 minutes.
There were 12,605 incidents of force against people by individual officers were registered in the three months…
