A mother has told of her fears... as search and rescue teams and police scour a stretch of river for a man missing for 12 days.

Kieron Knowlden, 25, was last seen after spending a night in Tonbridge on March 1.

CCTV footage has revealed his last known movements after leaving Mojo's bar at around 2am.

Now Kieron's mum has told of her anguish after he disappeared without a trace.

Speaking as search efforts are escalated, Kieron’s mother Donna Burchell said: "Nothing can be confirmed until they find him, but it would seem like he has fallen in.

"We are all totally devastated by this news and now finding it hard to come to terms with the idea we may never see him again."

Specialist diving teams have already been used to scour parts of the River Medway.

Surface water checks are also been carried out in areas between Cannon Lane bridge, River Walk and Town Lock, and along nearby footpaths and towpaths.

Now Kent Search and Rescue is planning to use an aircraft to take aerial images of the river.

It comes after police recently obtained CCTV footage, which shows his last known movements after leaving Mojo’s bar at around 2am.

"We are continuing to do everything we can to locate Kieron, but sadly the most probable line of enquiry is that he has fallen into the river and drowned" - Acting DI Kris Eberlein

Acting Detective Inspector Kris Eberlein said: "We are continuing to do everything we can to locate Kieron, but sadly the most probable line of enquiry is that he has fallen into the river and drowned.

"The footage shows Kieron walking, but appearing unsteady on his feet.

"He can be seen stumbling very close to a river bank near New Wharf Road.

"If Kieron had then emerged from this area we would have expected other cameras in the vicinity to pick up his movements.

"Unfortunately, although there is some CCTV still being reviewed, there have been no further sightings."

Acting DI Eberlein said there was no suggestion of foul play.

Relatives of Kieron have now also seen the CCTV.
