The police cordon at the junction of Old Dover Road and Nunnery Fields, Canterbury

Police investigating two bomb hoaxes in Canterbury have now identified all three women pictured on a CCTV image they released as part of their investigation.

Detectives say they have spoken to the trio since the image featured on the BBC's Crimewatch programme last week.

They have not been charged with any offences.

It follows confirmation that a 41-year-old woman and a 52-year-old man who were arrested last Friday have been released without charge.

Police would not confirm whether the woman was one of those identified from the CCTV image.

They are still trying to trace a man seen in other CCTV pictures, who they believe planted a suspect device in Marks and Spencer on August 26, bringing chaos to the city centre.

The device was discovered when a smoke grenade was set off shortly after another device, designed to look like a pipe bomb, was found near a railway line in Old Dover Road.

Det Ch Insp Tom Richards, who is leading the investigation, said: "I want to thank the public for the positive response to our media appeal last week and the useful information that have provided so far.

"We have a number of new lines of inquiry which are taking this investigation forward, and my team are working hard following up all the new leads and investigative opportunities we now have.

"I would still encourage anyone who thinks they have any information which could assist the investigation to get in touch, no matter how small or insignificant they think it could be.

"If you can help, please call the incident room on 01303 289600 or Kent Crimestoppers, anonymously, on 0800 555 111."
