Last night, images were released of the clothing he was wearing at the time of his disappearance: a pink Ralph Lauren polo shirt and brown suede Timberland boots.

The last confirmed sighting of Corrie is on Saturday September 24 at 3.20am on Brentgovel Street in Bury town centre.

Over the weekend, searches by RAF police, Suffolk police, the National Police Helicopter and Suffolk Lowland Search and Rescue volunteers have been carried out along the A134 between Bury and Honington and have now been extended further afield.

Enquiries and information received over the past week have also led police to believe he may have been in the Mildenhall area at some point between 4.30am and 8am on the Saturday morning. Officers are keen to hear from anyone who may have seen or spoken to a man matching Corrie's description in this area around this time.

Chief Inspector Steve Denham of Suffolk Police, said: 'This behaviour is totally out of character for Corrie and we are very concerned for his welfare.

'We are still examining CCTV in Bury St Edmunds town centre and urging any friends or members of the public who may have seen or spoken to Corrie over the course of the evening of September 23 and the early hours of September 24 in Bury St Edmunds to come forward.

'We are also appealing for people or drivers in the local area or further afield who may have seen him after our last confirmed sighting of him to contact us. Any information or conversation could be significant at this stage of the enquiry as we continue to piece together his movements.'
