The officer was responding to the 2020 terror attack in Streatham, south London.

PC Paul Fisher is now facing allegations that he drove dangerously after his unmarked police vehicle allegedly collided with three other vehicles and a garden wall during the fast-moving response operation. 

The 45-year-old officer is attached to the Met’s Specialist Firearms Command and was in the process of responding to the attack on February 2 2020 when he was involved in a crash on Streatham Common North. 

In 2020, the IOPC launched an investigation into him and another officer for gross misconduct and dangerous driving - they were both put on restricted duties. 

The IOPC investigation concluded in May 2021, and the CPS is not taking further action with regards to the second police driver whose marked police vehicle was in close proximity when the collision occurred. 

During the terror incident, Sudesh Amman, 20, was shot dead by armed undercover officers after he stole a knife from a hardware shop and stabbed two members of the public. 

Amman had been under round-the-clock armed surveillance prior to the attack as well as subject to 30 “stringent licence restrictions”. 

At Amman’s inquest last year, the senior Met officer leading the investigation, whose identity is protected, had said there was a lack evidence against him in the days before the attack. However he said that police actions on the day prevented further tragedy. 

The inquest had also heard how Amman was deemed to be “one of the most dangerous individuals” that police and MI5 teams had investigated, and that police feared an attack would be “when, not if” during discussions a fortnight ahead of his release.

The CPS has now authorised the charge against PC Fisher under section 2 of the Road Traffic Act. PC Fisher is due to attend Westminster Magistrates' Court on Monday.
