Video footage on social media of a man recklessly riding a motocross bike through busy Blenheim streets has lead to disqualification for the rider.
Detectives and road policing staff were made aware of the online video of the local man riding his bike, Senior Sergeant Peter Payne said.
Inquiries established the 23-year-old had been pulling wheelies on McKendry St in late December.
Police also discovered the man pulled a wheelie on his off-road bike for 90m down a busy, narrow street when he came into the CBD in February, the day before the annual Marlborough Wine and Food Festival, and a market day being hosted in The Forum in Market Square.
He pulled a wheelie down Market St until the intersection of Wynen St, Payne said.
"Market St was busy this day with pedestrians and vehicles, some of which were parked.
"This was a reckless act which put the safety of the public in jeopardy.
"Police are here to keep our communities safe, and will not hesitate to hold people to account when they put people's lives at risk."
The man has been disqualified from driving for six months and ordered to do 40 hours of community work.
