CHESHIRE Police are advising extra security measures will be in force during Saturday’s races at Chester.

The “MBNA Roman Day Races” will take place tomorrow – “an afternoon of non-stop racing alongside Roman-themed activities.”

Racegoers are advised there will be enhanced security checks on arrival including bags, cars and body searches.

Chief inspector Richard Rees, commander for Chester races, said: "With more than 25,000 racegoers expected to attend Chester this Saturday, I want to reassure everyone that they will see an increased police presence to ensure they have a safe and enjoyable time.

"Although there is no direct threat to the races, in light of the tragic events in Manchester we want Saturday to be extra secure to reassure and protect those attending.

"This means there will be extra security measures put in place with regular bag and transport searches as well as ticket checks being carried out.

“In order for these searches to be carried out efficiently, I would urge racegoers to arrive at the racecourse as soon as possible to avoid any delays and to be patient as it may take longer than normal to get into the racecourse.

“These security checks are being put in place to help increase public safety and provide greater protection to the event.

“Following the decision by the Prime Minister to raise the national threat level to critical, Operation Temperer has been activated and as a result racegoers may see an armed police presence.

“This isn't cause for alarm but for further visible reassurance.

“I also want to remind the public to stay alert, be extra vigilant.”

Any suspicious behaviour should be reported to a police officer, or call the Anti-Terror hotline: 0800 789 321.

In an emergency always dial 999.
