Officers are trying to jog people's memories about the last whereabouts of missing student Libby Squire.
Police insist the investigation to find Libby Squire remains a missing person’s enquiry, after arresting a man on suspicion of abduction.
Libby, a 21 year old Hull University Philosophy student from Buckinghamshire, hasn't been seen since the early hours of Friday.
Detectives have continued searching the area around the Oak Road playing fields and at Raglan Street, where the arrest was made.
They're launching a big media van at Cottingham Road, featuring images of Libby. Officers will be leafleting people around the area tonight.
