A man killed his parents before taking his own life in Westminster last year 'while the balance of his mind' as affected, an inquest has ruled.

Mohammed Achraf Amrani Marrakchi took his own life on February 13, 2015 after killing his parents the previous day.

The inquest into the deaths was held on Tuesday (August 9) which concluded that Amrani took his life, and unlawfully killed his parents, Hassan and Zohra Amrani.

Police misconduct

A Metropolitan Police officer has received a written warning for failing to carry out proper checks before Amrani killed his parents.

The Met referred the matter to the Independent Police Complaints Commission (IPCC) following the deaths, who launched an investigation into previous police contact with Amrani.

Amrani was jailed in 2010 at Southwark Crown Court for seven years after he filmed a sex attack on a young woman he had lured to his home and raped.

Commander Nick Downing said: “Our thoughts and sympathies remain with the Amramis' friends ands extended family at this incredibly difficult time.

“This is a tragic case and the MPS has fully co-operated with the IPCC investigation, having referred the matter to them at the earliest opportunity.”

'Significant factor in the deaths'

Amrani, who was formally known as Ashraf Amrani, was arrested for affray two days before he killed his parents, and was given street bail by a Metropolitan Police sergeant.

The jury ruled the decision to give Amrani street bail was a significant factor in the deaths of Mr and Mrs Amrani.

They also said that a police operation which monitor sex offenders released on licence from prison – Operation Jigsaw – and the probation service were not made aware of his arrest, which also contributed.

Officer issued written warning

Following the IPCC investigation, the police sergeant was issued a written warning for misconduct for failing to carry out a risk assessment.

The IPCC also recommended a policy be put in place to ensure Jigsaw units are informed as soon as one of their subjects is arrested, bailed or charged.

Another recommendation was made to ensure street bail is authorised by a custody sergeant.

The Met said the first reccomendation is now enforced and new rules say officers must consider risk factors in more detail.

'What lessons can be learnt'

Commander Downing added: “It is only right the circumstances surrounding the death of Amrani and his parents have been examined by an independent body to see what lessons can be learnt and reassure the local community that measures are being taken to improve our practices.

“The recommendations will make our policies and processes far more robust in the future.”
