A 24-year-old man has been arrested on suspicion of abducting Libby Squire - a week since she vanished without a trace - as police search his home for signs of the missing Hull student.
Detectives said last night they are investigating 'all possibilities' amid growing local fears that she may have been abducted.
Now a suspect has been held on suspicion of forcibly taking her away against her will on the night of Thursday January 31.
Last night, the man was arrested at a house in Raglan Street, Hull, a short walk from Libby was last seen a week ago.
Officers have also towed away a silver Vauxhall Astra from the street outside the property at 10pm and remain at his property this morning where they were taking photographs inside.
A witness to the arrest, who lives on the street, and watched out of the window, told MailOnline: 'There were loads of police in the house and you could see the flash of cameras at they took pictures of the rooms. At around 10pm they took away the Vauxhall Astra on the back of a lorry. We're all in shock'.
Jorge Ramos, 22, who lives next door to the raided property, said: 'I think a family live there. I knew there had been searches around the university for Libby, but I never imagined that someone would be arrested on this street'.
Libby had been on a drunken night out with friends and returned to her student digs in a taxi at 11.30pm last Thursday after being turned away from a nightclub.
Instead of going inside, CCTV revealed that Libby went to sit on a bench around 300 yards away on Beverley Road. She was last seen on an adjacent street, Beresford Avenue, at just after midnight before disappearing and a near-neighbour of Libby's said she woke up suddenly having heard 'blood-curdling screams' at around 12.30am.
It has also emerged today that a man in a balaclava was seen near Libby's home.
