Police urge people on CCTV to come forward.
Police searching for Hull University student Libby Squire, have renewed their appeal for four people, seen on CCTV footage in the Oak Road area, to come forward.
It's been six weeks since the 21 year old was last seen in the Beverley Road area. Her family say they're really struggling to come to terms with what's happened. Police say the public support has been staggering and that hundreds of leads have been followed up.
Detectives have re-released the footage to encourage possible witnesses to come forward. They say Libby's disappearance remains unexplained.
