'Plans in place' to deal with any Grand National disruption
The festival returns to Aintree later this week
Ahead of 150,000 people descending on Aintree for the Grand National later this week, police say they have plans in place to prevent any significant disruption.
The three-day festival is one of the biggest events in the Merseyside calendar every year, with thousands also watching across the world.
Those going are being warned to expect security searches on arrival - with only pre-booked vehicles allowed onto the site.
Chief Inspector Kevin Chadderton said:
"As with every year, we are expecting many visitors to the region to enjoy this festival of racing, which is a prime opportunity to showcase many of the great things Merseyside has to offer.
"As with all big events, we carry out extensive planning alongside all partner organisations in the run up, to ensure everyone who attends the races has a great time, stays safe, and it is memorable for all the right reasons.
"Racegoers and other visitors can help us and the racecourse staff by giving themselves extra time to get to the course and limiting the number of bags and other items they bring along. Everyone should expect to undergo the normal security checks. I’d like to thank people in advance for their patience and cooperation in these essential checks. Your safety is our priority.
"Criminal activity will not be tolerated"
"There are plans in place to deal with any incidents that may arise and to prevent any significant or ongoing disruption to spectators, local residents and businesses.
"Anti-social behaviour, hate crime, disorder and other criminal activity will not be tolerated and will be dealt with robustly. If you see someone acting suspiciously or committing a crime, then please speak to an officer on patrol or contact us directly.
"I would also ask visitors to consider residents who live near the racecourse and treat the area with respect.
"We will be deploying Project Servator officers in uniform and plain-clothes. These officers are specially trained to spot the tell-tale signs that someone may have criminal intent, such as gathering information that may help them plan or prepare to commit a crime.
"These deployments will appear at any time in and around the area of the racecourse, but the public should not be alarmed by this. Officers will be encouraging racegoers to help us make this a safe and enjoyable event by being our extra eyes and ears and to report anything suspicious to us."
The force is asking people to report any concerns to a police officer or member of racecourse staff, by calling 101, or by calling the anti-terrorist hotline on 0800 789 321.
