Do you recognise this man? CCTV captures a man on camera in Canterbury city centre on Friday.

Police investigating two bomb hoaxes in Canterbury on Friday evening have released CCTV images of a man they want to speak to.

Described as white, aged 35 to 40 years old, 5ft 9in to 6ft tall, the man was pictured in three separate locations in the city on Friday afternoon.

He was wearing dark clothing which appears to be cycling apparel including leggings and cycling shoes and a dark baseball cap.

He was carrying a blue and black rucksack.

An investigation team set up after the events on Friday night is making steady progress.

Officers continue to follow a number of positive lines of enquiry, including forensic evidence gathered at both scenes.

Two areas of the city were cordoned off after the discovery of the hoax devices sparked evacuations. Old Dover Road, between Nunnery Fields and St Lawrence Road, was closed following the discovery of a suspicious device on the railway line. The city centre, from St George's Street to The Parade, was also closed from early evening.

Hundreds of staff from shops and businesses were evacuated after a small fire in Marks & Spencer led to the discovery of a second hoax device.

Kent Police is also renewing its appeal for witnesses, who were in Canterbury city centre on Friday afternoon to come forward.

Assistant Chief Constable Andy Adams said: "There were hundreds of people in Canterbury city centre on Friday afternoon and we are very keen to hear from anyone who witnessed any suspicious behaviour, particularly in and around Marks & Spencer and the railway line in Old Dover Road.

"This is a very serious crime and one which caused considerable disruption to the people of Canterbury.

"I am very grateful to residents for their patience and perseverance and also for the many messages of public support thanking us for bringing the situation under control and for keeping people updated both in the media and on our Twitter and Facebook sites.

"I am determined to bring whoever was responsible for causing this disruption before the courts and we continue to do all they can and identify the offender.

"I would urge anyone who can identify the man in the CCTV images or has any other information to get in touch."
