A criminal manslaughter investigation has been launched against a police officer over the death of a man who fell from a window.
Ayuub Hassan Abdi, 34, fell from an attic bedroom window of a property in Lozells, Birmingham, on September 6. He died of his injuries in hospital the following day.
The Independent Office for Police Conduct (IOPC) says it is investigating a police officer serving in West Midlands Police for a range of offences, including manslaughter.
The watchdog said: “A constable has now been informed that he is being criminally investigated for unlawful homicide, common assault and assault occasioning actual bodily harm, in relation to the use of force during the incident.”
“The officer has also been served with a gross misconduct notice for possible breaches of police professional conduct standards.
“It does not necessarily mean that criminal charges or disciplinary proceedings will follow.”
The Crown Prosecution Service describes unlawful homicide as an offense where a person intentionally does an unlawful and dangerous act which unintentionally results in death.
The IOPC added: “Our inquiries so far have established that police went to a multi-occupancy house in Lansdowne Road following a report that two residents there had been attacked by a man with a knife.
“After the arrival of another police unit, two officers went upstairs to speak to Mr Abdi, who was in his bedroom on the third floor.
“The evidence indicates that during the conversation Mr. Abdi moved toward an open window and one of the officers then discharged a Taser.
“Moments later, Mr Abdi fell from the window, landing on the ground outside. An ambulance took him to the hospital with serious injuries.”
The warden was alerted to the incident the same day and immediately began his investigation.
A post-mortem examination was carried out a week later, with the results of the toxicology report still to be returned. An investigation will be launched in due course.
Derrick Campbell, the watchdog's director for the West Midlands, said: “We have been in contact with Mr Abdi's family to express our support and explain our role. Our thoughts are with them and all those affected by his death.
“We will conduct a thorough, independent investigation into all the circumstances of Mr Abdi's death.
“This will include a review of the actions and decision-making of the officers present.
“The police can use force in the course of their duties and we will consider whether any force used was reasonable, necessary and proportionate.
“Once our investigation is complete, we will decide whether to refer the matter to the Crown Prosecution Service for a charging decision and determine whether any officers should face disciplinary action.”
West Midlands Police have been approached for comment.
