COPS have revealed the last known sighting of a student who vanished from a pub and may have walked alongside a river.
Sebastian, 21, was last seen leaving the Black Horse Pub in Chippenham, Wiltshire, at about 11.30pm on Thursday night.
CCTV footage then captured the young man heading towards Lovers Walk.
Cops now believe Sebastian went south along Avon Valley Walk towards his home address in Notton.
In a new update officers urged anyone who may have CCTV or Ring doorbells between Notton and Chippenham to check their footage from that night.
Chippenham Police also asked any drivers who could have been in the south Chippenham and Rowden Hill area at 11.30pm on Thursday, into the early hours of Friday morning, to review their dashcam recordings.
The force added: “We are also asking if there are any residents with wildlife cameras along the river to please get in touch.”
Sebastian is described as white, around 5ft 10ins tall, slim build, with blonde/brown hair with a long fringe.
He was last seen wearing a grey jumper, blue jeans, a beige fur lined jacket and white Adidas trainers.
County Chief Inspector Ben Huggins said: “Sebastian has now been missing since late on Thursday evening and we and his family are extremely worried about him.
“Finding him is a Force priority and we are utilising extensive resources to locate him, including exploring different routes he may have taken.
“Volunteers from other agencies are also heavily involved in the search and I would like to thank them for their efforts. I also ask that members of the public don’t fly any drones near them to ensure that they are able to conduct their searches effectively.
“Sebastian’s family are being supported by specially trained officers.
“If you see Sebastian, or know anything about his whereabouts or disappearance, please report it on 999 quoting log 141 of February 28.”
