The last known movements of Pat Lamb have been recreated on video to encourage new witnesses to come forward.

It shows younger brother Paul Lamb, 27, in similar clothes to the ones the broadcast engineer was wearing when he went missing after a night out in Maidstone on Friday, December 12.

Put together by the KM Group, it has been released as the search for 28-year-old looks set to continue into a fifth week.

Sister Zoe Lamb, 20, said: "If anyone who was out that night can look back at the footage of the reconstruction that we have made and really think back to see if they can remember a man who was on his own and looked a bit unsteady, the smallest piece of information could bring us to finding him again.

"Patrick's last sighting was at 12.20am at Fairmeadow. His phone last pinged at 1.34am within a five-mile radius of Wyke Manor Road.

"We need people to think if they remember seeing him after this time because this will help us retrace his footsteps."

Older brother Jamie added: "Patrick if you're watching, please get in touch. Let us know you're ok because everyone is really worried about you.

"Someone must have seen him on that night. Someone must know, even just the smallest detail."

Ch Insp Susie Harper, district commander for Maidstone, said: "We are acting on the information that we have got available to us.

"It may be that someone with that reconstruction will possibly come forward and say yes they remembered him and he was a little bit further along."

Earlier today the Pat Lamb search team revealed they have received a possible new clue.

A lorry driver has reported seeing a man wearing a black jacket, dark trousers and shoes in Forstal Road, close to the Village Hotel on the night he disappeared.

For the past two days the family have been trying to get their search trending on social media.

This has come from two coordinated efforts, the first at midnight on Thursday, January 8 and the second at 6am today.

Celebrities including Eastenders' Danny-Boy Hatchard, Neighbours' Alan Fletcher and Coronation Street's Kym Marsh have shown their support retweeting posts.
