The Met’s investigation was launched last August when prison staff found a drone that had crashed inside HMP Pentonville.
It was found with cannabis, Pregabalin, the drug Spice and mobile phones in it.
Detectives linked this drone with another drone that had crashed in HMP Coldingley in Woking in July 2023.
Drugs and a phone were also recovered from that drone.
Detective Inspector Zara Baker said: “Smuggling drugs into prison is a serious crime.
“Illegal drugs massively increase the risk of violence towards staff and other inmates and ruins rehabilitation.
“As the public would expect, we are disrupting the supply of illegal drugs and have a number of methods to crack down on those who try and break the law.
“Anyone with information about those who profit from the misery caused by illegal drugs is asked to contact police or Crimestoppers.”
Met officers worked closely with counterparts at HM Prison Service and SEROCU (South East Regional Organised Crime Unit) and used forensic techniques and other tactics to identify the suspect.
They also linked the incident to crashed drones containing drugs and phones found at HMP Pentonville in September 2023, HMP High Down in Banstead in November 2023 and HMP Swaleside, Kent in January of this year.
A man has been charged in connection with the offences.
