A Swedish man who used Twitter to alert police of speeding drivers on a road near his house got a response – which came in the form of a hefty speeding fine the next day.
Henrik Ismarker noticed that like himself, his local police were active on the social media network Twitter.
He tweeted to the Söderort police Twitter account , informing them that a road near his house in Stockholm was often frequented by lead-footed drivers.
"People drive too fast in the area and that's why I asked the police to set up a control," Ismarker told.
The police responded promptly on Twitter, agreeing that the road needed some form of speed control, especially as there was a school on the street.
The very next day, the man was driving along the road in question when he was pinged for driving 42 kilometres an hour in a 30 zone.
This resulted in a 2,400 kronor fine ($358), and a no doubt red-faced police informer.
Ismarker tweeted the police the next day, saying "Nice that you were there already today. Unfortunately, this became expensive for me".
When the police confirmed that he had, indeed, been caught speeding on the street, he responded: "This couldn't be a bigger fail then. But thanks for the lesson."
When probed about the feeling of getting caught in his own trap, Ismarker tells it was "embarrassing, stupid, and a good lesson".
However, he's still pleased with overall response, even if it did leave him out of pocket.
"I'm very satisfied with the police response," Ismarker said.
"They were very professional both in traffic regulating and with Twitter," he told.
