A 24-year-old man has been arrested on suspicion of abduction in connection with the disappearance of missing Hull University student Libby Squire.
Humberside Police said the man was arrested at an address in Raglan Street, Hull, on Wednesday night and is now helping them with their enquiries.
On Thursday morning a lone police car stood outside the terraced property.
John Garrity said police arrived at his home on the street at around 9.15pm on Wednesday.
"The police knocked on the door and showed me their warrant card, that was two officers, and they wanted to gain access to the garden.
"There's a fence panel down, so I suggested the easiest way for them to do that was through my garden and then to walk through the gap where the fence panel had fallen," Mr Garrity said.
Mr Garrity added that he does not know the inhabitants of the house that the police were trying to access, but said that many of the properties on the street are rented.
A spokeswoman said 21-year-old Miss Squire has still not been found.
She was reported missing from the city in the early hours of Friday morning and an intensive search has been mounted by police and volunteers over the last week.
The officer involved in the search include a specialist marine unit who have been souring local waterways.
The wooded area of park, yards from where Miss Squire was last seen, is also being examined.
A statement from Humberside Police said finding Libby - who went missing in the early hours of last Friday - remains their "top priority".
"A 24-year-old man has been arrested in connection with the disappearance of Hull student Libby Squire," a spokesperson said.
"Officers made the arrest at an address in Raglan Street, Hull, last night.
"The man remains in our custody, assisting us with our enquires.
"We have not yet found Libby and doing so remains our top priority.
"Libby's parents have been informed of the man's arrest and we're continuing to support them at this difficult time."
The address where the man was arrested is about half-a-mile from Miss Squire's home.
Police say they have received hundreds of calls in the last week.
In a tweet police said they will drive a 11sq metre screen around the local area showing Miss Squire's face, in the hopes of getting more information.
Officers have said Miss Squire was dropped off in a taxi near her home on Wellesley Avenue at around 11.29pm on Thursday January 31 and was seen 10 minutes later on CCTV near a bench on Beverley Road, where a motorist stopped to offer help.
She is believed to have been in this area until around 12.09am on Friday.
On Wednesday, Miss Squire's parents Lisa and Russ issued a statement which said: "We'd like to thank everyone who has helped this week in trying to find Libby.
"We have been overwhelmed with people's kindness and support and it's been incredible how all her friends, students at the university, and members of the public have joined together to help us look for her."
Humberside Police said Mr and Mrs Squire, from High Wycombe, Buckinghamshire, had met their daughter's friends and university staff.
