A man who was killed by police in Islington on Friday was hit by two bullets fired by the same officer.

A post mortem on Monday found that the man, in his 40s, died from shock and haemorrhage as the result of a gunshot wound to the back of the left chest.

He had also suffered a bullet wound to his upper left arm.

The ongoing Independant Police Complaints Commission (IPCC) investigation in to the incident found that both bullets were fired by one Met marksman.

Police shot the knife-wielding 40-year-old in Shepperton Road at about 1am after he had taken his former partner hostage in her own home.

It is believed that the woman, in her 50s, had a restraining order against him due to a history of domestic abuse.

The IPCC say that a witness statement has been taken from the woman and that of the officer who shot the man and that it appears that she was being held at knifepoint against a wall inside the flat during the incident.

Statements have been provided by officers who attended the incident and are currently being analysed by IPCC investigators. The officer who fired the shots and a number of others have been requested to attend interviews by IPCC investigators over the coming days.

The man cannot be named at this stage as he has not been formally identified.

Cindy Butts, IPCC commissioner, said: “I have today met with members of the bereaved family, who are very distressed, to extend my condolences and to update them on the progress of our investigation.

“I would like to assure all those concerned that the circumstances surrounding this tragedy will be investigated thoroughly.”

An inquest in to the death is expected to be opened this week.
