Any vehicles leaving a locked down city will be halted by police to help prevent the coronavirus spreading further, it has been claimed.
Officers will be allowed to stop unessential travel out of Leicester - the UK's first city to see a local lockdown imposed.
Vehicles will turned around if deemed necessary, while patrols in public areas such as parks are to be increased to help enforce new guidelines, reports MirrorOnline.
Those hoping to flout the local lockdown to sneak into neighbouring areas for a night out after pubs and restaurants reopen at the weekend could be hit with £100 fines.
Craig Guildford, chief constable of Nottinghamshire Police said: "We are not anticipating a rise [in travel] of people from Leicester.
"You are still allowed to travel to get to work, but they will be looking for a breach of the guidance such as going shopping or going on a night out."
