A warning has been issued over a new viral social media trend that could see people "killed and seriously injured".
The trend, called the "100pmh speed challenge", sees drivers attempt to hit high ultra high speeds and record their speedometers on Snapchat, before posting the evidence to their stories for others to see.
The trend has been circulating for a couple of years, but has recently got the attention of the police again, North Wales Live reports.
It comes as there have been recent reports of anti-social driving and speeding, which the police have said is a cause for "real concern".
Officers from the Roads Policing Unit have been carrying out checks in recent weeks, particularly the Llan-y-Pwll link road in Wrexham.
Sergeant Leigh Evans of the Roads Policing Unit said: "We are aware of the concerns raised regarding speeding and nuisance vehicles in the area.
"We are continuing to monitor the area closely with regular patrols. Speeding is an issue that concerns many residents and one that we take extremely seriously. Those who choose to ignore the speed limits can expect to be prosecuted for their actions.
"The public will say ‘police need to prioritise real issues, or ‘shouldn’t they focus on real crimes?’
"I want to stress that people are killed and seriously injured as a result of unnecessary speed, so this is quite rightly, a priority for us.
"The 100mph challenge that we have been made aware of is a real concern. Nobody needs to be reminded that speeding can have devastating consequences."
The police also warned people that there was no excuse for breaking the law, whether you're taking part in a social media "challenge" or not.
They said that driving at dangerous speeds could be harmful to other drivers and themselves, and accidents could put extra pressure on the NHS.
If prosecuted for speeding, the minimum penalty is a £100 fine and three penalty points. You could also be disqualified from driving if you build up 12 or more penalty points within a period of three years.
Plus if you get just six points in the first two years after passing your test, you will lose your licence.
