Police have seized an electric scooter after the rider was caught for a second time.
Officers came across the rider by Reach Free School in Mill End.
Three Rivers Police posted on its Facebook page: “Rickmansworth Safer Neighbourhood Team found this rider using a mechanically propelled vehicle on the pavement near to the school.
“Officers stopped the rider and established that they had previously been spoken to about the use of the e scooter and had been issued with a section 59 warning.
“Due to previous warning being given, E scooter was seized under section 60 of the road traffic act.”
The post was accompanied by a picture of the scooter along with a police vehicle parked to the entrance to the school in Uxbridge Road.
Police in Hertfordshire have been cracking down on the use of illegal e-scooters, saying they are being “ridden antisocially” and are “putting people in danger”.
Privately owned e-scooters are currently illegal on public roads and pavements in the UK, but people hiring them as part of a government trial are allowed to ride them so long as they have a valid driving license.
PCSO Clare Andrews, from the Bishop’s Stortford and Sawbridgeworth safer neighbourhood team in East Hertfordshire, said: “Over the past few months, we have received numerous complaints from members of the public about e-scooters being used illegally and putting people in danger.
“With trials of rented e-scooters taking place around the country, some people are purchasing them in the mistaken belief they can legally use them on public paths and roads. This is not the case and we are finding that otherwise law-abiding citizens are inadvertently breaking the law in this way.
“However, we are also seeing them being ridden anti-socially by young people who know full well that they should not be using them.”
