The widow of PC Dave Phillips has visited the scene of his death, two days after he was struck by a car and killed during a pursuit in Merseyside.

The 34-year-old died after being hit by a pick-up vehicle that mounted a central reservation in Wallasey on Monday.

His widow Jen and their daughters Abigail, seven, and Sophie, three, laid flowers at the side of the road.

Two men aged 18 and 30 are being held on suspicion of murder.

Two women aged 19 and 34, both from Wallasey, have also been arrested on suspicion of assisting an offender.

PC Phillips had been trying to stop a red Mitsubishi Challenger, which was driven from an estate agents in Birkenhead.

The married father-of-two had been responding to reports of a burglary in Woodchurch Road, Birkenhead.

He and a colleague had been attempting to stop the vehicle using a tyre-puncturing “stinger” device at 02:10 BST.

Fellow officers tried to save his life before he was rushed to hospital, but he died shortly after arrival.

The pick-up vehicle was found abandoned in Corbyn Street, Wallasey at 02:55.
