Police continue investigation into Anita Rose's murder

Why it matters: The operation targeted criminals using Ipswich's road network while also focusing on dangerous driving behaviours that contribute to fatal collisions.

The big picture: The intelligence-led operation involved nine partner agencies and took place on Tuesday, 22 April at a check site at Sainsbury's in Hadleigh Road, aiming to disrupt organised crime groups that operate across county borders.

By the numbers:

• 71 vehicles were escorted to the check site, with just 14 found clear of offences

• 63 Traffic Offence Reports were issued at the site

• 129 additional speeding offences were detected in surrounding areas

• Five vehicles were seized for various offences

The details: Police made four arrests, including three for drug-driving and one for a suspect wanted by Lincolnshire Police for theft. Immigration Enforcement made five further arrests after checking 51 people.

Officers focused on the "Fatal Four" offences that commonly cause serious accidents: drink/drug driving, mobile phone use, speeding, and not wearing a seatbelt.

A motorcyclist was recorded travelling at 81mph in a 40mph zone on the A1214 London Road.

What they're saying: Sergeant Alex Kelly of the Roads and Armed Policing Team said: "Days of action like this are vital in helping us gather and share intelligence with partner agencies, and are also a great way of intensely targeting an area."

"I have attended far too many collisions where one of the 'Fatal Four' elements was a contributing factor, some of which have resulted in the loss of a loved one."

Suffolk's Police and Crime Commissioner Tim Passmore added: "The number of arrests and traffic offences recorded show just how valuable these multi-agency days of actions are."

"I fully support these pro-active campaigns. They send out a strong, clear message to those who choose not to comply with the 'fatal four' that Suffolk Constabulary is on the case."

The bottom line: The operation was part of the National Police Chiefs' Council's Operation Spotlight, which focuses on criminal use of the road network and targets those committing the most dangerous driving offences.
