Six more Met Police officers are being investigated after inappropriate photos were allegedly taken of a 'murdered' Bucks social worker and her sister in a London park.

Buckinghamshire Council social worker Bibaa Henry, 46, and her sister Nicole Smallman were found stabbed to death in Fryent Country Park in Wembley on June 7.

Eighteen-year-old Danyal Hussein from Blackheath in south east London has been charged with their murders.

In June, the Independent Office of Police Conduct (IOPC) announced it was investigating two police officers who had been arrested on suspicion of misconduct in a public office after claims emerged they had taken "non-official" photographs of the crime scene.

However, the IOPC's investigation has revealed six further Metropolitan Police officers were allegedly aware of, or had received or viewed the photographs and did not challenge or report them.

The investigation has also uncovered further alleged misconduct breaches of the standards of professional behaviour for a small number of officers which include honesty and integrity, and equality and diversity.

These alleged breaches are not related to the murder investigation.

The IOPC says further lines of enquiry are still being looked at and they are liaising closely with Bibaa and Nicole's family.

IOPC Director for London Sal Naseem said: “I am deeply concerned by the issues emerging from our investigation.

“Policing is founded on community consent, confidence and cooperation.

"The public have a right to expect high standards of professional behaviour from police.

"These allegations, if true, breach that trust and may point to more serious issues around the organisational culture, which we will also be looking at.

“The evidence we have seen provides a salient reminder to all police officers to take responsibility for addressing wrongdoing and upholding professional standards in their own ranks, and their obligation to speak out if they see unacceptable behaviour.”

When the two officers were initially arrested, Bibaa and Nicole's mother Mina Smallman said the pictures "dehumanised" her children, adding: "This has taken our grief to another place."
