An object swallowed by a father of one whose death after a struggle with police sparked violent scenes did not contain drugs, according to forensic analysis.

CCTV appeared to show at least one police officer attempting to restrain Rashan Charles, 20, on the floor of a shop in east London before he died later in hospital on July 22.

His death sparked violent clashes with police in Hackney on Friday as demonstrators hurled bottles and fireworks at officers.

Did not swallow drugs: CCTV shows Rashan Jermaine Charles, 20, (circled) putting his hand to his mouth as he entered a Hackney shop moments before a policeman tackled him

The police watchdog has now said the object 'did not contain a controlled substance' but that findings from a pathologist are yet to come back.

Last week, the Independent Police Complaints Commission (IPCC) said the evidence it had seen so far suggested that Mr Charles was detained by a Metropolitan Police officer who had followed him on foot into a shop on Kingsland Road after an earlier attempted vehicle stop.

The officer restrained Mr 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.

A spokesman said today: 'The IPCC's investigation into the circumstances of Rashan Charles's death following contact with police in Hackney on 22 July is ongoing and making good progress.

'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.

'The IPCC has now received results of forensic analysis of an object that was removed from Rashan's airway by paramedics. The object did not contain a controlled substance.'

The watchdog said IPCC staff met with Mr Charles's family on Wednesday afternoon to update them with the results of the forensic analysis.

The spokesman added: 'A post mortem took place on Monday 24 July and the IPCC is awaiting the preliminary findings from the pathologist.'

Weyman Bennett, co-convenor at Stand Up To Racism, said: 'We now know that the initial statements put out at the time of Rashan's death were misleading or outright lies. Justification for his death looks increasingly at the hands of those people that forcibly restrained him.

'The attempt to smear Rashan as somebody involved in drugs was an attempt to assassinate his character. We hold the police wholly responsible for these false statements that were put out, and we demand justice for Rashan.'

Furious campaigners set fire to bins and blocked roads outside a London police station last week as they protested against the handling of Mr Charles.

Up to 150 people chanting 'no justice, no peace' while holding Black Lives Matters placards had brought traffic to a standstill outside east London's Stoke Newington Police Station in a vigil for Mr Charles.

The vigil was organised by Stand Up To Racism, with campaigners saying they are 'enormously concerned and angered' over his death.

The crowd, which was made up of people from different races and ages, listened to speeches about alleged police brutality as uniformed officers looked on.

Rashan's father Patrick Charles said: 'I'm a father but my son was killed in the hands of police. Me and my family are grieving over this.

'I thank everyone for their support, it's a comfort to us to read your messages.

'We are seeking justice on this but I want everybody to be peaceful. This is not something we are going to take into our own hands.'
