New CCTV footage has been released of the two suspects in the Salisbury Nerve Agent attack.

The pictures from March 4th, show the pair, known as Alexander Petrov and Ruslan Boshirov, in the city after novichok had been placed at the home of Sergei Skripal.

The first CCTV clip shows the two suspects as they arrive at Salisbury train station on Sunday 4 March at around 11:48hrs.

The second clip shows the suspects at approximately 11:58hrs walking past a petrol station in Wilton Road, which is in the vicinity of the Skripals’ home address. This is just prior to when detectives believe the nerve agent was placed on the door handle.

The third clip shows the two men walking over a bridge on Fisherton Street at approximately 13:00 hours before they eventually return to Salisbury train station and travel back to Heathrow and catch a flight to Moscow later that night.

Images showing the fake perfume bottle apparently used in the attack have also been released. Five people were poisoned in the aftermath, including Dawn Sturgess, who later died.

"Since we, alongside the CPS, announced details of the two suspects in September, our investigation has continued at pace.
