An investigation has been launched following a disturbance at an address in Hackney.
Police were called at 21:43hrs on Tuesday, 19 March to Knights Close, Hackney following reports of a domestic disturbance at a residential address.
A 28-year-old man was reported to be armed with knives and making threats to kill.
Specialist firearms officers attended the scene.
One officer sustained a stab injury. Firearms officers were deployed and a male was shot by police.
He was conveyed to an east London hospital, where he currently remains. At this time, his condition is critical.
The officer's injury is not believed to be life-threatening. He has not been hospitalised. There were no other reported injuries.
The Met's Directorate of Professional Standards has been informed and will be supporting the Independent Office for Police Conduct who have launched an independent investigation.
As a result of subsequent searches at the address, both in connection with the police investigation into the assault on the officer, and the IOPC investigation into the shooting, a suspected hand grenade and suspected firearm were discovered. A number of local properties were then evacuated as a precaution and specialist officers assessed the devices. The devices were deemed safe and removed from the property. The Met’s Central East Command Unit has launched a parallel criminal investigation, to the IOPC independent investigation, into the assault and firearms matters.
