A man was shot dead by police during an operation relating to a suspected plot to free a prisoner.
The 28-year-old was shot close to the back of Wood Green Crown Court, north London, at about 09:00 GMT.
The incident took place as Erwin Amoyaw-Gyamfi, 29, and Erun Izzet, 32, were due to be transported to the court in a custody van for sentencing.
Two people were arrested near Bracknell Close on suspicion of conspiring to help someone escape from custody.
Sentencing has gone ahead for Izzet and Amoyaw-Gyamfi, relating to an attempted “professional hit” in October.
They had previously pleaded guilty to a range of offences, including possession of a sub-machine gun and possession of a self loading pistol and bullets with the intent to endanger life.
The court heard they were intercepted by police on their way to “kill, maim or wound” someone on 13 October 2015.
There was a heavy police presence inside and outside the court as Judge Nicholas Browne QC sentenced the pair to 14 years each.
In granting their particular wish to be sentenced today, he said: “I completely ignore and put out of my mind the serious incident outside the court area, not far from where I am”.
The Met said the operation in Wood Green was “intelligence-led” and had resulted in the arrests of four people in total.
The two arrested near Bracknell Close were aged 30 and 19.
In nearby Barratt Avenue, police also arrested a 31-year-old and a 25-year-old. The Met said these were “related” arrests but did not specify the nature.
Following the shooting, police cordoned off the road at the junction of Bracknell Close and Olympus Grove, near Winkfield Road.
A white forensics tent was erected in the residential street and officers wearing balaclavas were at the scene.
An air ambulance was also called but the man was confirmed dead shortly before 10:30 GMT.
There were no reports of any other injuries.
