TRAVELLERS have poured onto two car parks near to Derby County's iPro Stadium.
More than 40 caravans, vans and trucks piled onto bays to the right of DW Sports Fitness Club and outside the city's new Velodrome building.
Some moved onto the sites on Saturday and the rest arrived yesterday.
Barriers were left open, enabling the travellers to set up camp.
Janie Berry, director of legal and democratic services at Derby City Council, said the council would be "serving them personally with notice to leave the site" shortly after 3pm today.
She added: "Travellers sometimes leave shortly after service of the notice referred to above.
"If they do not, we will apply to the court for a possession hearing.
"The date of the hearing is not something we can determine, and it can take several days or more to get a hearing date.
"Travellers sometimes leave when the court gives them notice of the hearing date, or on the actual hearing date. If they do not, we then have to ask the court for a warrant to forcibly remove them.
"We have no control over the date of eviction, which is subject to the availability of the bailiffs.
"It can be as much as 2 weeks, often less but sometimes more. In all, if the travellers do not comply, the whole process can take 2 or 3 weeks.
"The barriers are always left open at night to enable vehicles to exit the car park. In the day, access can be gained by pressing the button next to the barrier."
Some 15 caravans were parked up in a council-owned public car park next to DW Sports Fitness Club, while another six were on parking bays for the velodrome.
There were a further 20 vans and trucks spread across both car parks.
Some of the vehicles had Irish number plates.
A Derbyshire police spokesman said the group, who had been at Tibshelf Services on the M1 earlier on Sunday before moving south, would be monitored.
It is thought the travellers had previously come from the annual Appleby horse fair, in Cumbria.
The Derby Telegraph went to the scene at 8.45am.
There was little sign of life, although sleeping adults could be seen through the open windows of some caravans.
A couple of kids were wondering around the car park in bare feet.
Rubbish bags were beginning to mount up, while washing was hung out to dry.
